Abstract

To secure good communication quality in data transmission using an LDPC code.SOLUTION: In group-wise interleaving, an LDPC code with a code length N of 69120 bits is interleaved in units of 360-bit bit groups 0 to 191. In the group-wise interleaving, a sequence in the LDPC code after the group-wise interleaving is returned to the original sequence. The present techniques are applicable, e.g., to data transmission using an LDPC code.SELECTED DRAWING: Figure 126

Description

  The present technology relates to a transmission method and a reception device, and more particularly, to a transmission method and a reception device that can ensure good communication quality in data transmission using an LDPC code, for example.

  LDPC (Low Density Parity Check) code has a high error correction capability.In recent years, for example, DVB (Digital Video Broadcasting) -S.2 in Europe, DVB-T.2, DVB-C.2, Widely adopted in transmission systems for digital broadcasting such as ATSC (Advanced Television Systems Committee) 3.0 in the United States (see, for example, Non-Patent Document 1).

  Recent studies have shown that LDPC codes can achieve performance close to the Shannon limit as the code length is increased, similar to turbo codes and the like. In addition, since the LDPC code has the property that the minimum distance is proportional to the code length, its characteristic is that the block error probability characteristic is good, and furthermore, the so-called error floor phenomenon observed in the decoding characteristic such as turbo code is observed. An advantage is that it hardly occurs.

  In data transmission using an LDPC code, for example, the LDPC code is used as a symbol of orthogonal modulation (digital modulation) such as QPSK (Quadrature Phase Shift Keying), and the symbol is used as a signal point of orthogonal modulation. Mapped and sent.

  Data transmission using the LDPC code as described above is spreading worldwide, and it is required to ensure good communication (transmission) quality.

  The present technology has been made in view of such a situation, and is intended to ensure good communication quality in data transmission using an LDPC code.

  In the first receiving device of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from data transmitted by the first transmission method is returned to the original order.

In the second transmission method of the present technology, LDPC encoding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and an encoding rate r of 3/16. Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to any one of 16 signal points of 16 QAM (Quadrature Amplitude Modulation) UC (Uniform Constellation) in units of 4 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

It has become.

  In the fourth receiving apparatus of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from the data transmitted by the fourth transmission method is returned to the original order.

In the fifth transmission method of the present technology, LDPC coding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and a coding rate r of 7/16, and the LDPC code is converted to 360 Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to one of 64 signal points of 64QAM (Quadrature Amplitude Modulation) 2D-NUC (Non-Uniform Constellation) in units of 6 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

  In the fifth reception device of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from data transmitted by the fifth transmission method is returned to the original order.

In the sixth transmission method of the present technology, LDPC encoding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and an encoding rate r of 3/16. Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to any one of 256 signal points of UC (Uniform Constellation) of 256QAM (Quadrature Amplitude Modulation) in units of 8 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

  In the seventh receiving apparatus of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from the data transmitted by the seventh transmission method is returned to the original order.

In the eighth transmission method of the present technology, LDPC encoding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and an encoding rate r of 3/16. Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to any one of 1024 signal points of 1D-NUC (Non-Uniform Constellation) of 1024QAM (Quadrature Amplitude Modulation) in units of 10 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

  In the ninth receiving device of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from data transmitted by the ninth transmission method is returned to the original order.

In the tenth transmission method of the present technology, LDPC encoding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and an encoding rate r of 3/16. Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to any of 4096 signal points of UC (Uniform Constellation) of 4096QAM (Quadrature Amplitude Modulation) in units of 12 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

  In the tenth receiving device of the present technology, the arrangement of the LDPC codes after group-wise interleaving obtained from the data transmitted by the tenth transmission method is returned to the original order.

In the eleventh transmission method of the present technology, LDPC coding is performed based on a parity check matrix of an LDPC code having a code length N of 69120 bits and a coding rate r of 7/16, and the LDPC code is converted to 360 Group-wise interleaving is performed in which bits are interleaved in bit group units. The LDPC code is mapped to any of 4096 signal points of UC (Uniform Constellation) of 4096QAM (Quadrature Amplitude Modulation) in units of 12 bits. In the group-wise interleaving, the bit group 0 to 191 of the 69120-bit LDPC code is a bit group, where the i + 1-th bit group from the beginning of the LDPC code is a bit group i.

  Hereinafter, embodiments of the present technology will be described, but before that, LDPC codes will be described.

  <LDPC code>

  Note that the LDPC code is a linear code and does not necessarily need to be binary, but will be described here as being binary.

  The LDPC code is characterized in that the parity check matrix defining the LDPC code is sparse. Here, a sparse matrix is a matrix in which the number of “1” s in the matrix is very small (a matrix in which most elements are 0).

  FIG. 1 is a diagram illustrating an example of a parity check matrix H of an LDPC code.

  In the parity check matrix H in FIG. 1, the weight of each column (column weight) (the number of “1”) (weight) is “3”, and the weight of each row (row weight) is “6”. .

  In the encoding by LDPC code (LDPC encoding), for example, a generator matrix G is generated based on the check matrix H, and the generator matrix G is multiplied by binary information bits to generate a codeword (LDPC code). ) Is generated.

Specifically, an encoding apparatus that performs LDPC encoding first calculates a generator matrix G that holds the expression GH ^T = 0 between the transposed matrix H ^T of the parity check matrix H. Here, when the generator matrix G is a K × N matrix, the encoding device multiplies the generator matrix G by a bit string (vector u) of information bits made up of K bits to generate a code made up of N bits. The word c (= uG) is generated. The code word (LDPC code) generated by this encoding device is received on the receiving side via a predetermined communication path.

  LDPC code decoding is an algorithm proposed by Gallager called probabilistic decoding (Probabilistic Decoding), which consists of a variable node (also called a message node) and a check node. This can be done by a message passing algorithm based on belief propagation on a so-called Tanner graph. Here, hereinafter, the variable node and the check node are also simply referred to as nodes as appropriate.

  FIG. 2 is a flowchart showing a procedure for decoding an LDPC code.

In the following, a real value (reception LLR) expressing the “0” likelihood of the value of the i-th code bit of the LDPC code (one codeword) received on the receiving side as a log likelihood ratio as appropriate. ) _Is also referred to as a received value u _0i . Further, a message output from the check node is u _j and a message output from the variable node is v _i .

First, in the decoding of the LDPC code, as shown in FIG. 2, in step S11, the LDPC code is received, the message (check node message) u _j is initialized to “0”, and the counter of the iterative process is used. The variable k taking the integer of is initialized to “0”, and the process proceeds to step S12. In step S12, a message (variable node message) v _i is obtained by performing the calculation (variable node calculation) shown in Expression (1) based on the received value u _0i obtained by receiving the LDPC code. Based on the message v _i , the message u _j is obtained by performing the calculation (check node calculation) shown in Expression (2).

Here, d _v and d _c in Equation (1) and Equation (2) can be arbitrarily selected to indicate the number of “1” s in the vertical direction (column) and horizontal direction (row) of the parity check matrix H, respectively. Parameter. For example, in the case of an LDPC code ((3,6) LDPC code) for a parity check matrix H having a column weight of 3 and a row weight of 6 as shown in FIG. 1, d _v = 3, d _c = 6 Become.

It should be noted that in the variable node calculation of Expression (1) and the check node calculation of (2), the message input from the edge (line connecting the variable node and the check node) to which the message is to be output, respectively. Are not subject to computation, the computation range is 1 to d _v -1 or 1 to d _c -1. In addition, the check node calculation of equation (2) actually creates a table of function R (v ₁ , v ₂ ) shown in equation (3) defined by one output for two inputs v ₁ and v ₂ in advance. In addition, this is performed by using it continuously (recursively) as shown in Equation (4).

  In step S12, the variable k is further incremented by “1”, and the process proceeds to step S13. In step S13, it is determined whether or not the variable k is larger than a predetermined iterative decoding count C. If it is determined in step S13 that the variable k is not greater than C, the process returns to step S12, and thereafter the same processing is repeated.

On the other hand, if it is determined in step S13 that the variable k is larger than C, the process proceeds to step S14, and a message v _i as a decoding result to be finally output is obtained by performing the calculation shown in equation (5). And the LDPC code decoding process ends.

Here, unlike the variable node calculation of equation (1), the calculation of equation (5) is performed using messages u _j from all branches connected to the variable node.

  FIG. 3 is a diagram illustrating an example of a parity check matrix H of a (3, 6) LDPC code (coding rate 1/2, code length 12).

  In the parity check matrix H in FIG. 3, the column weight is 3 and the row weight is 6, as in FIG. 1.

  FIG. 4 is a diagram illustrating a Tanner graph of the parity check matrix H of FIG.

  Here, in FIG. 4, a check node is represented by plus “+”, and a variable node is represented by equal “=”. Check nodes and variable nodes correspond to the rows and columns of the parity check matrix H, respectively. The connection between the check node and the variable node is an edge, and corresponds to “1” of the check matrix element.

  That is, when the element in the j-th row and the i-th column of the parity check matrix is 1, the i-th variable node (“=” node) from the top and the j-th check node (“” from the top in FIG. 4). + "Node") are connected by a branch. The branch represents that the sign bit corresponding to the variable node has a constraint condition corresponding to the check node.

  In a sum product algorithm, which is a decoding method of an LDPC code, a variable node operation and a check node operation are repeatedly performed.

  FIG. 5 is a diagram illustrating variable node calculation performed in the variable node.

In the variable node, the message v _i corresponding to the branch to be calculated is the variable node of the formula (1) using the messages u ₁ and u ₂ from the remaining branches connected to the variable node and the received value u _0i. It is obtained by calculation. Messages corresponding to other branches are obtained in the same manner.

  FIG. 6 is a diagram illustrating a check node calculation performed in the check node.

  Here, the check node calculation of Expression (2) is performed using the relationship of Expression a × b = exp {ln (| a |) + ln (| b |)} × sign (a) × sign (b), Equation (6) can be rewritten. However, sign (x) is 1 when x ≧ 0, and −1 when x <0.

・・・（６）

... (6)

When the function φ (x) is defined as the equation φ (x) = ln (tanh (x / 2)) when x ≧ 0, the equation φ ⁻¹ (x) = 2 tanh ⁻¹ (e ^−x ) holds. Equation (6) can be transformed into Equation (7).

・・・（７）

... (7)

  In the check node, the check node calculation of Expression (2) is performed according to Expression (7).

That is, in the check node, as shown in FIG. 6, the message u _j corresponding to the branch to be calculated is the messages v ₁ , v ₂ , v ₃ , v ₄ , v from the remaining branches connected to the check node. _It is obtained by the check node calculation of Equation (7) using ₅ . Messages corresponding to other branches are obtained in the same manner.

Note that the function φ (x) in the equation (7) can be expressed by the equation φ (x) = ln ((e ^x +1) / (e ^x −1)), and when x> 0, φ (x ) = Φ ⁻¹ (x). When the functions φ (x) and φ ⁻¹ (x) are mounted on hardware, they may be mounted using a LUT (Look Up Table), but both are the same LUT.

  <Configuration example of transmission system to which this technology is applied>

  FIG. 7 shows a transmission system to which the present technology is applied (a system is a logical collection of a plurality of devices, regardless of whether or not each component device is in the same housing). It is a figure which shows the structural example of embodiment.

  In FIG. 7, the transmission system includes a transmission device 11 and a reception device 12.

  The transmission device 11 transmits (broadcasts) (transmits) a television broadcast program, for example. That is, the transmission device 11 encodes target data to be transmitted, such as image data and audio data as a program, into an LDPC code, for example, a satellite line, a terrestrial wave, a cable (wired line), or the like. It transmits via the communication path 13.

  The receiving device 12 receives the LDPC code transmitted from the transmitting device 11 via the communication path 13, decodes it into the target data, and outputs it.

  Here, it is known that the LDPC code used in the transmission system of FIG. 7 exhibits extremely high capability in an AWGN (Additive White Gaussian Noise) communication channel.

  On the other hand, a burst error or erasure may occur in the communication path 13. For example, in particular, when the communication channel 13 is a terrestrial wave, in an OFDM (Orthogonal Frequency Division Multiplexing) system, D / U (Desired to Undesired Ratio) is 0 dB (Undesired = echo power is equal to Desired = main path power) ), The power of a specific symbol may become erasure according to the delay of an echo (path other than the main path).

  Also, even if flutter (communication path where delay is 0 and doppler frequency is applied) is added, if D / U is 0 dB, depending on the Doppler frequency, OFDM at a specific time There are cases where the power of the entire symbol becomes zero (erasure).

  Furthermore, a burst error may occur due to the state of the wiring from the receiving unit (not shown) such as an antenna that receives a signal from the transmitting device 11 to the receiving device 12 on the receiving device 12 side, or the power supply instability of the receiving device 12. May occur.

On the other hand, in the decoding of the LDPC code, in the variable node corresponding to the column of the parity check matrix H and thus the code bit of the LDPC code, as shown in FIG. 5, the code bit of the LDPC code (the received value u _0i ) Since the variable node calculation of Expression (1) involving addition is performed, if an error occurs in the sign bit used for the variable node calculation, the accuracy of the required message is reduced.

  In the decoding of the LDPC code, the check node performs the check node calculation of Expression (7) using the message obtained by the variable node connected to the check node, so that a plurality of connected variable nodes ( When the number of check nodes in which the error (including erasure) of the code bits of the LDPC code corresponding to) simultaneously increases, the decoding performance deteriorates.

  That is, for example, if two or more of the variable nodes connected to the check node become erasures simultaneously, the check node sends a message with an equal probability of a probability of 0 and a probability of 1 to all the variable nodes. return. In this case, a check node that returns an equiprobable message does not contribute to one decoding process (one set of variable node calculation and check node calculation), and as a result, requires a large number of repetitions of the decoding process. As a result, the decoding performance deteriorates, and the power consumption of the receiving apparatus 12 that decodes the LDPC code increases.

  Therefore, in the transmission system of FIG. 7, it is possible to improve the resistance to burst errors and erasures while maintaining the performance of the AWGN communication path (AWGN channel).

  <Configuration Example of Transmitting Device 11>

  FIG. 8 is a block diagram illustrating a configuration example of the transmission device 11 of FIG.

  In the transmission apparatus 11, one or more input streams (Input Streams) as target data are supplied to a mode adaptation / multiplexer (Mode Adaptation / Multiplexer) 111.

  The mode adaptation / multiplexer 111 performs processing such as mode selection and multiplexing of one or more input streams supplied thereto as necessary, and supplies the resulting data to a padder 112. .

  The padder 112 performs necessary zero padding (Null insertion) on the data from the mode adaptation / multiplexer 111 and supplies the resulting data to a BB scrambler 113.

  The BB scrambler 113 subjects the data from the padder 112 to BB scramble (Base-Band Scrambling), and supplies the data obtained as a result to the BCH encoder (BCH encoder) 114.

  The BCH encoder 114 BCH-encodes the data from the BB scrambler 113, and supplies the data obtained as a result to an LDPC encoder 115 as LDPC target data that is a target of LDPC encoding.

  The LDPC encoder 115 performs LDPC encoding on the LDPC target data from the BCH encoder 114, for example, according to a parity check matrix having a dual diagonal structure, which is a portion corresponding to the parity bit of the LDPC code. To output an LDPC code having LDPC target data as information bits.

  That is, the LDPC encoder 115 defines the LDPC target data in a predetermined standard such as DVB-S.2, DVB-T.2, DVB-C.2, ATSC 3.0 (in the check matrix). (Corresponding) LDPC code and other LDPC codes are encoded, and the resulting LDPC code is output.

  Here, the LDPC code defined in the DVB-S.2 and ATSC 3.0 standards is an IRA (Irregular Repeat Accumulate) code, and the parity matrix (part or all) in the parity check matrix of the LDPC code is It has a staircase structure. The parity matrix and the staircase structure will be described later. As for IRA codes, for example, “Irregular Repeat-Accumulate Codes,” H. Jin, A. Khandekar, and RJ McEliece, in Proceedings of 2nd International Symposium on Turbo codes and Related Topics, pp. 1-8, Sept. 2000.

  The LDPC code output from the LDPC encoder 115 is supplied to a bit interleaver 116.

  The bit interleaver 116 performs bit interleaving described later on the LDPC code from the LDPC encoder 115 and supplies the LDPC code after the bit interleaving to a mapper 117.

  The mapper 117 maps the LDPC code from the bit interleaver 116 to a signal point representing one symbol of orthogonal modulation in units of one or more code bits (symbol unit) of the LDPC code and performs orthogonal modulation (multiple modulation). Value modulation).

  That is, the mapper 117 converts the LDPC code from the bit interleaver 116 on the constellation, which is an IQ plane defined by an I axis representing an I component in phase with a carrier wave and a Q axis representing a Q component orthogonal to the carrier wave. The quadrature modulation is performed by mapping to signal points determined by the modulation method for performing quadrature modulation of the LDPC code.

When the number of constellation signal points used in the orthogonal modulation method performed by the mapper 117 is 2 ^m , the mpp code bit of the LDPC code is used as a symbol (one symbol), and the mapper 117 The LDPC code from the bit interleaver 116 is mapped in symbol units to signal points representing symbols among 2 ^m signal points.

  Here, as a modulation method of the orthogonal modulation performed by the mapper 117, for example, a modulation method defined in the DVB-S.2 or ATSC3.0 standard, or the like, for example, BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 8PSK (Phase-Shift Keying), 16APSK (Amplitude Phase-Shift Keying), 32APSK, 16QAM (Quadrature Amplitude Modulation), 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM, 4PAM (Pulse Amplitude Modulation) etc. In the mapper 117, which modulation method is used for orthogonal modulation is set in advance in accordance with, for example, the operation of the operator of the transmission apparatus 11.

  Data obtained by processing in the mapper 117 (mapping result obtained by mapping symbols to signal points) is supplied to a time interleaver 118.

  The time interleaver 118 performs time interleaving (interleaving in the time direction) on a symbol-by-symbol basis for the data from the mapper 117, and the resulting data is converted into SISO / MISO encoders (SISO / MISO (Single Input Single Output / Multiple). Input Single Output) encoder) 119.

  The SISO / MISO encoder 119 performs space-time coding on the data from the time interleaver 118 and supplies the data to a frequency interleaver 120.

  The frequency interleaver 120 performs frequency interleaving (interleaving in the frequency direction) on a symbol-by-symbol basis for the data from the SISO / MISO encoder 119, and supplies the data to a frame builder / resource allocation unit (Frame Builder & Resource Allocation) 131.

  On the other hand, the BCH encoder 121 is supplied with control data (signalling) for transmission control such as BB signaling (Base Band Signaling) (BB Header).

  The BCH encoder 121 performs BCH encoding on the control data supplied thereto in the same manner as the BCH encoder 114, and supplies the resulting data to the LDPC encoder 122.

  The LDPC encoder 122 performs LDPC encoding on the data from the BCH encoder 121 as LDPC target data in the same manner as the LDPC encoder 115 and supplies the resulting LDPC code to the mapper 123.

  Similar to the mapper 117, the mapper 123 maps the LDPC code from the LDPC encoder 122 to a signal point that represents one symbol of orthogonal modulation in units of one or more code bits (symbol unit) of the LDPC code. Then, quadrature modulation is performed, and data obtained as a result is supplied to the frequency interleaver 124.

  Similar to the frequency interleaver 120, the frequency interleaver 124 performs frequency interleaving on the data from the mapper 123 in units of symbols and supplies the data to the frame builder / resource allocation unit 131.

  The frame builder / resource allocation unit 131 inserts pilot symbols at necessary positions of the data (symbols) from the frequency interleavers 120 and 124, and from the resulting data (symbols), a predetermined number A frame composed of a number of symbols (for example, a PL (Physical Layer) frame, a T2 frame, a C2 frame, etc.) is configured and supplied to an OFDM generation unit (OFDM generation) 132.

  The OFDM generation unit 132 generates an OFDM signal corresponding to the frame from the frame from the frame builder / resource allocation unit 131, and transmits the OFDM signal via the communication path 13 (FIG. 7).

  Note that the transmission apparatus 11 is configured without providing some of the blocks illustrated in FIG. 8 such as the time interleaver 118, the SISO / MISO encoder 119, the frequency interleaver 120, and the frequency interleaver 124, for example. Can do.

  <Configuration Example of Bit Interleaver 116>

  FIG. 9 is a block diagram illustrating a configuration example of the bit interleaver 116 of FIG.

  The bit interleaver 116 has a function of interleaving data, and includes a parity interleaver 23, a group-wise interleaver 24, and a block interleaver 25.

  The parity interleaver 23 performs parity interleaving for interleaving the parity bits of the LDPC code from the LDPC encoder 115 to the positions of other parity bits, and supplies the LDPC code after the parity interleaving to the group-wise interleaver 24.

  The groupwise interleaver 24 performs groupwise interleaving on the LDPC code from the parity interleaver 23, and supplies the LDPC code after the groupwise interleaving to the block interleaver 25.

  Here, in group-wise interleaving, an LDPC code for one code is partitioned from the beginning into 360-bit units equal to a parallel factor P described later, and the one-part 360 bits are used as a bit group to generate a parity interleaver 23. Are interleaved in bit group units.

  When group-wise interleaving is performed, the error rate can be improved compared to when group-wise interleaving is not performed, and as a result, good communication quality can be ensured in data transmission.

  The block interleaver 25 performs block interleaving for demultiplexing the LDPC code from the group-wise interleaver 24, so that, for example, an LDPC code for one code is converted into an m-bit symbol that is a unit of mapping. And supplied to the mapper 117 (FIG. 8).

  Here, in block interleaving, for example, a column as a storage area for storing a predetermined number of bits in the column (vertical) direction is equal to the number m of symbol bits in the row (horizontal) direction. The LDPC code from the group-wise interleaver 24 is written in the column direction and read out in the row direction for the storage areas arranged only in this manner, so that the LDPC code is symbolized into m-bit symbols.

  <LDPC code check matrix>

  FIG. 10 is a diagram illustrating an example of a parity check matrix H used for LDPC encoding by the LDPC encoder 115 of FIG.

The parity check matrix H has an LDGM (Low-Density Generation Matrix) structure, and among the code bits of the LDPC code, an information matrix H _A corresponding to the information bits and a parity matrix H _T corresponding to the parity bits And can be expressed by the formula H = [H _A | H _T ] (a matrix having the information matrix H _A as the left element and the parity matrix H _T as the right element).

  Here, the number of information bits and the number of parity bits in the code bits of one LDPC code (one code word) are referred to as an information length K and a parity length M, respectively, and one (1 The number of code bits of the LDPC code of the code word is called a code length N (= K + M).

The information length K and the parity length M for an LDPC code having a certain code length N are determined by the coding rate. Also, the parity check matrix H is a matrix in which rows × columns are M × N (a matrix having M rows and N columns). Then, the information matrix H _A, becomes the matrix of M × K, the parity matrix H _T is a matrix of M × M.

Figure 11 is a diagram showing an example of a parity matrix H _T of the parity check matrix H used in LDPC encoding by the LDPC encoder 115 of FIG.

The parity matrix H _T of the parity check matrix H used in LDPC encoding by the LDPC encoder 115, for example, the same parity matrix H _T and the check matrix H of an LDPC code prescribed in standards such as DVB-T.2 Can be adopted.

DVB-T.2 like parity matrix H _T of the parity check matrix H of an LDPC code of which is specified in the Standard, as shown in FIG. 11, first element is, so to speak a matrix of step structure arranged stepwise (lower bidiagonal matrix). The row weight of the parity matrix H _T is 1 for the first row and 2 for all the remaining rows. The column weight is 1 for the last column and 2 for all the remaining columns.

As described above, LDPC codes of the check matrix H the parity matrix H _T has a staircase structure can be using the check matrix H, readily produced.

That is, an LDPC code (one codeword), together represented by a row vector c, and column vector obtained by transposing the row vector is represented as c ^T. In addition, in the row vector c that is an LDPC code, an information bit portion is represented by a row vector A, and a parity bit portion is represented by a row vector T.

  In this case, the row vector c is represented by the expression c = [A | T] (the element of the row vector A is the left element, and the row vector T is represented by the row vector A as information bits and the row vector T as parity bits. Can be represented by a row vector with the right element as the right element.

And the check matrix H, the row vector c = as LDPC codes | and [A T], it is necessary to satisfy the expression Hc ^T = 0, = such expression Hc ^T = 0 to satisfy the row vector c [A | T] to the row vector T as parity bits which constitute check matrix H = | when [H _a H _T] parity matrix H _T of the parity has a staircase structure shown in FIG. 11, in the formula Hc ^T = 0 By sequentially setting the elements in each row to 0 from the element in the first row of the column vector Hc ^T , it can be obtained sequentially (in order).

  FIG. 12 is a diagram for explaining a parity check matrix H of an LDPC code defined in a standard such as DVB-T.2.

  For the KX column from the first column of the LDPC code parity check matrix H specified in the DVB-T.2 standard, the column weight is X, and for the subsequent K3 column, the column weight is 3, and then For the M-1 column, the column weight is 2, and for the last column, the column weight is 1.

  Here, KX + K3 + M-1 + 1 is equal to the code length N.

  13 is a diagram illustrating the number of columns KX, K3, and M, and the column weight X for each coding rate r of the LDPC code defined in the DVB-T.2 standard and the like.

  Standards such as DVB-T.2 define LDPC codes with a code length N of 64800 bits and 16200 bits.

  For an LDPC code having a code length N of 64,800 bits, 11 code rates (nominal rates) 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3 / 4, 4/5, 5/6, 8/9, and 9/10 are defined, and for an LDPC code having a code length N of 16200 bits, 10 coding rates 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, and 8/9 are specified.

  Hereafter, the code length N of 64800 bits is also referred to as 64k bits, and the code length N of 16200 bits is also referred to as 16k bits.

  As for the LDPC code, the error rate tends to be lower as the code bit corresponding to the column having the larger column weight of the check matrix H.

  In the parity check matrix H defined in the standard such as DVB-T.2 shown in FIG. 12 and FIG. 13, the column weight on the head side (left side) tends to be large. As for the LDPC code corresponding to H, the first code bit tends to be more resistant to errors (tolerant to errors), and the last code bit tends to be weaker to errors.

  <Parity interleave>

  The parity interleaving by the parity interleaver 23 of FIG. 9 will be described with reference to FIGS.

  FIG. 14 is a diagram illustrating an example of (part of) a Tanner graph of a parity check matrix of an LDPC code.

  As shown in FIG. 14, when two or more of the variable nodes (corresponding code bits) connected to the check node simultaneously cause errors such as erasures, all the check nodes are connected to the check node. A message having a probability that the value is 0 and the probability that the value is 1 is returned to the variable node. For this reason, if a plurality of variable nodes connected to the same check node simultaneously become erasures or the like, the decoding performance deteriorates.

Incidentally, an LDPC code output from the LDPC encoder 115 of FIG. 8, for example, similarly to the LDPC code prescribed in standards such as DVB-T.2, an IRA code, the parity matrix H _T of the parity check matrix H As shown in FIG. 11, it has a staircase structure.

FIG. 15 is a diagram illustrating an example of a parity matrix H _T having a staircase structure and a Tanner graph corresponding to the parity matrix H _T as illustrated in FIG.

15A shows an example of a parity matrix H _T having a staircase structure, and FIG. 15B shows a Tanner graph corresponding to the parity matrix H _T of A in FIG.

In parity matrix H _T has a staircase structure, in each row (except the first row) first element is adjacent. Therefore, in the Tanner graph of the parity matrix H _T, the value of the parity matrix H _T corresponding to the columns of two adjacent elements are set to 1, the two variable nodes adjacent, connected to the same check node Yes.

  Therefore, if a parity error corresponding to the two adjacent variable nodes mentioned above simultaneously becomes an error due to a burst error, an erasure, or the like, two variable nodes (using the parity bit) corresponding to the two parity bits that are in error. Since the check node connected to the variable node that seeks the message returns the message having the same probability of 0 and 1 to the variable node connected to the check node, the decoding performance is improved. to degrade. When the burst length (the number of parity bits that continuously cause an error) increases, the number of check nodes that return messages with equal probability increases, and the decoding performance further deteriorates.

  Therefore, the parity interleaver 23 (FIG. 9) performs parity interleaving for interleaving the parity bits of the LDPC code from the LDPC encoder 115 to the positions of other parity bits in order to prevent the above-described degradation in decoding performance. .

Figure 16 is a diagram illustrating a parity matrix H _T of the parity check matrix H corresponding to the LDPC code after parity interleave to the parity interleaver 23 of FIG. 9 is performed.

Here, the information matrix H _A of the parity check matrix H corresponding to the LDPC code output from the LDPC encoder 115 is the same as the information matrix of the parity check matrix H corresponding to the LDPC code defined in the standard such as DVB-T.2. In addition, it has a cyclic structure.

  A cyclic structure is a structure in which a column matches a cyclic shift of another column.For example, for each P column, the position of 1 in each row of the P column is the first of the P column. A structure in which the column is cyclically shifted in the column direction by a predetermined value such as a value proportional to the value q obtained by dividing the parity length M is also included. Hereinafter, the P column in the cyclic structure is referred to as a parallel factor as appropriate.

  As described in FIGS. 12 and 13, there are two types of LDPC codes having a code length N of 64800 bits and 16200 bits as LDPC codes defined in the DVB-T.2 standard. For both of the two types of LDPC codes, the parallel factor P is defined as 360 which is one of the divisors of the parity length M except 1 and M.

  The parity length M is a value other than the prime number represented by the equation M = q × P = q × 360, using a value q that varies depending on the coding rate. Therefore, similarly to the parallel factor P, the value q is another one of the divisors of the parity length M except 1 and M, and the parity length M is divided by the parallel factor P. (The product of P and q, which is a divisor of the parity length M, becomes the parity length M).

  As described above, the parity interleaver 23 sets the information length to K, sets x to an integer between 0 and less than P, and sets y to an integer between 0 and less than q. Of the code bits of the code, the K + qx + y + 1-th code bit is interleaved at the position of the K + Py + x + 1-th code bit.

  The K + qx + y + 1-th code bit and the K + Py + x + 1-th code bit are both the K + 1-th code bit and the subsequent parity bits, and are therefore parity bits. According to interleaving, the position of the parity bit of the LDPC code is moved.

  According to such parity interleaving, the variable nodes connected to the same check node (corresponding parity bits) are separated by a parallel factor P, that is, 360 bits here, so that the burst length is less than 360 bits. In this case, it is possible to avoid a situation in which a plurality of variable nodes connected to the same check node cause an error at the same time, and as a result, it is possible to improve resistance to burst errors.

  Note that the LDPC code after parity interleaving that interleaves the K + qx + y + 1-th code bit at the position of the K + Py + x + 1-th code bit is K + qx + of the original parity check matrix H. This coincides with the LDPC code of a parity check matrix (hereinafter also referred to as a transform parity check matrix) obtained by performing column replacement for replacing the y + 1th column with the K + Py + x + 1th column.

  Further, as shown in FIG. 16, a pseudo cyclic structure with P columns (360 columns in FIG. 16) as a unit appears in the parity matrix of the conversion parity check matrix.

  Here, the pseudo cyclic structure means a structure in which a part except a part has a cyclic structure.

  The parity check matrix obtained by performing column replacement equivalent to parity interleaving on the parity check matrix of the LDPC code specified in the DVB-T.2 standard, etc. is 360 rows × In the 360-column part (shift matrix described later), there is only one element of 1 (it is an element of 0). In that respect, it is not a (perfect) cyclic structure, but a pseudo cyclic structure. ing.

  The conversion parity check matrix for the LDPC code parity check matrix output from the LDPC encoder 115 has, for example, a pseudo cyclic structure, similar to the conversion parity check matrix for the LDPC code parity check matrix stipulated in a standard such as DVB-T.2. ing.

  In addition to the column replacement corresponding to parity interleaving with respect to the original check matrix H, the conversion check matrix in FIG. 16 replaces rows so that the conversion check matrix is configured with a configuration matrix described later. (Row replacement) is also applied to the matrix.

  FIG. 17 is a flowchart for explaining processing performed by the LDPC encoder 115, the bit interleaver 116, and the mapper 117 of FIG.

  The LDPC encoder 115 waits for the LDPC target data to be supplied from the BCH encoder 114, encodes the LDPC target data into an LDPC code in step S101, and supplies the LDPC code to the bit interleaver 116. The process proceeds to step S102.

  In step S102, the bit interleaver 116 performs bit interleaving on the LDPC code from the LDPC encoder 115, supplies a symbol obtained by the bit interleaving to the mapper 117, and the process proceeds to step S103.

  That is, in step S102, in the bit interleaver 116 (FIG. 9), the parity interleaver 23 performs parity interleaving for the LDPC code from the LDPC encoder 115, and converts the LDPC code after the parity interleaving to the group-wise interleave. Supplied to Lever 24.

  The groupwise interleaver 24 performs groupwise interleaving on the LDPC code from the parity interleaver 23 and supplies it to the block interleaver 25.

  The block interleaver 25 performs block interleaving on the LDPC code after group-wise interleaving by the group-wise interleaver 24, and supplies the m-bit symbol obtained as a result to the mapper 117.

In step S103, the mapper 117 maps the symbol from the block interleaver 25 to one of 2 ^m signal points determined by the orthogonal modulation method performed by the mapper 117, and performs quadrature modulation. Data is supplied to the time interleaver 118.

  As described above, by performing parity interleaving and group-wise interleaving, it is possible to improve an error rate when transmitting a plurality of code bits of an LDPC code as one symbol.

  Here, in FIG. 9, for convenience of explanation, the parity interleaver 23 that is a block that performs parity interleaving and the group-wise interleaver 24 that is a block that performs group-wise interleaving are configured separately. The parity interleaver 23 and the group-wise interleaver 24 can be configured integrally.

  That is, both parity interleaving and group-wise interleaving can be performed by writing and reading code bits to and from the memory, and an address (write address) for writing code bits is an address for reading code bits. It can be represented by a matrix to be converted into (read address).

  Therefore, if a matrix obtained by multiplying a matrix representing parity interleaving and a matrix representing groupwise interleaving is obtained, parity interleaving is performed by converting the sign bit using those matrices, and further, A result of group-wise interleaving the LDPC code after parity interleaving can be obtained.

  In addition to the parity interleaver 23 and the group-wise interleaver 24, the block interleaver 25 can also be configured integrally.

  That is, block interleaving performed by the block interleaver 25 can also be represented by a matrix that converts the write address of the memory storing the LDPC code into the read address.

  Therefore, if a matrix obtained by multiplying a matrix representing parity interleaving, a matrix representing groupwise interleaving, and a matrix representing block interleaving is obtained, the parity interleaving, groupwise interleaving, and block are determined by these matrices. Interleaving can be performed collectively.

  Note that one or the amount of parity interleaving and group-wise interleaving may not be performed.

  <Configuration example of LDPC encoder 115>

  FIG. 18 is a block diagram illustrating a configuration example of the LDPC encoder 115 of FIG.

  Note that the LDPC encoder 122 of FIG. 8 is similarly configured.

  As described with reference to FIG. 12 and FIG. 13, the DVB-T.2 standard specifies two types of code length N LDPC codes of 64800 bits and 16200 bits.

  For LDPC codes having a code length N of 64,800 bits, eleven coding rates 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4 / 5, 5/6, 8/9, and 9/10 are defined, and for LDPC codes with a code length N of 16200 bits, 10 coding rates 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, and 8/9 are defined (FIGS. 12 and 13).

  For example, the LDPC encoder 115 performs encoding (error correction coding) using an LDPC code having a code length N of 64,800 bits or 16200 bits for each code length N and each code rate. This can be performed according to the prepared check matrix H.

  In addition, the LDPC encoder 115 can perform LDPC encoding according to a parity check matrix H of an LDPC code having an arbitrary code length N and an arbitrary coding rate r.

  The LDPC encoder 115 includes an encoding processing unit 601 and a storage unit 602.

  The encoding processing unit 601 includes an encoding rate setting unit 611, an initial value table reading unit 612, a parity check matrix generation unit 613, an information bit reading unit 614, an encoded parity calculation unit 615, and a control unit 616, and an LDPC encoder The LDPC encoding of the LDPC target data supplied to 115 is performed, and the resulting LDPC code is supplied to the bit interleaver 116 (FIG. 8).

  That is, the coding rate setting unit 611 sets, for example, the code length N of the LDPC code, the coding rate r, and other specific information for specifying the LDPC code in accordance with an operator's operation or the like.

  The initial value table reading unit 612 reads, from the storage unit 602, a parity check matrix initial value table, which will be described later, representing a parity check matrix of an LDPC code specified by the specific information set by the coding rate setting unit 611.

The parity check matrix generation unit 613 generates a parity check matrix H based on the parity check matrix initial value table read by the initial value table reading unit 612 and stores it in the storage unit 602. For example, the check matrix generation unit 613 includes the information matrix H _A corresponding to the information length K (= code length N−parity length M) corresponding to the code length N and the coding rate r set by the coding rate setting unit 611. A check matrix H is generated by arranging 1 element in the column direction at a period of 360 columns (parallel factor P), and stored in the storage unit 602.

  The information bit reading unit 614 reads (extracts) information bits for the information length K from the LDPC target data supplied to the LDPC encoder 115.

  The encoded parity calculation unit 615 reads the parity check matrix H generated by the parity check matrix generation unit 613 from the storage unit 602, and uses the parity check matrix H to calculate a parity bit for the information bits read by the information bit reading unit 614, A codeword (LDPC code) is generated by calculating based on the formula.

  The control unit 616 controls each block configuring the encoding processing unit 601.

  The storage unit 602 stores, for example, a plurality of parity check matrix initial value tables corresponding to a plurality of coding rates and the like shown in FIGS. 12 and 13 for code lengths N such as 64800 bits and 16200 bits, respectively. Has been. The storage unit 602 temporarily stores data necessary for the processing of the encoding processing unit 601.

  FIG. 19 is a flowchart for explaining an example of processing of the LDPC encoder 115 of FIG.

  In step S201, the coding rate setting unit 611 sets code length N and coding rate r for performing LDPC coding, and specific information for identifying other LDPC codes.

  In step S202, the initial value table reading unit 612 stores a predetermined parity check matrix initial value table specified by the code length N, the encoding rate r, and the like as specific information set by the encoding rate setting unit 611. , Read from the storage unit 602.

  In step S203, the parity check matrix generation unit 613 uses the parity check matrix initial value table read from the storage unit 602 by the initial value table reading unit 612, and sets the code length N and the coding rate set by the coding rate setting unit 611. The parity check matrix H of the LDPC code of r is obtained (generated), supplied to the storage unit 602 and stored.

  In step S204, the information bit reading unit 614 uses the information length K (= N) corresponding to the code length N and the coding rate r set by the coding rate setting unit 611 from the LDPC target data supplied to the LDPC encoder 115. Xr) information bits are read, and the check matrix H obtained by the check matrix generation unit 613 is read from the storage unit 602 and supplied to the encoded parity calculation unit 615.

  In step S205, the encoded parity calculation unit 615 sequentially calculates the parity bits of the codeword c satisfying Equation (8) using the information bits from the information bit reading unit 614 and the check matrix H.

Hc ^T = 0
... (8)

In the formula (8), c represents a row vector as the codeword (LDPC code), c ^T represents the transpose of the row vector c.

  Here, as described above, in the row vector c as the LDPC code (one code word), the information bit portion is represented by the row vector A and the parity bit portion is represented by the row vector T. The row vector c can be expressed by the equation c = [A | T] by a row vector A as information bits and a row vector T as parity bits.

And the check matrix H, the row vector c = as LDPC codes | and [A T], it is necessary to satisfy the expression Hc ^T = 0, = such expression Hc ^T = 0 to satisfy the row vector c [A | T] to the row vector T as parity bits which constitute check matrix H = | when [H _a H _T] parity matrix H _T of the parity has a staircase structure shown in FIG. 11, in the formula Hc ^T = 0 By sequentially setting the elements in each row to 0 from the element in the first row of the column vector Hc ^T , it can be obtained sequentially.

  The encoded parity calculation unit 615 obtains a parity bit T for the information bit A from the information bit reading unit 614, and a codeword c = [A | T] represented by the information bit A and the parity bit T Is output as an LDPC encoding result of information bit A.

  Thereafter, in step S206, the control unit 616 determines whether or not to end LDPC encoding. If it is determined in step S206 that the LDPC encoding is not terminated, that is, for example, if there is still LDPC target data to be LDPC encoded, the process returns to step S201 (or step S204). The processing from S201 (or step S204) to S206 is repeated.

  In addition, when it is determined in step S206 that LDPC encoding is to be ended, that is, for example, when there is no LDPC target data to be LDPC encoded, the LDPC encoder 115 ends the processing.

  For LDPC encoder 115, a parity check matrix initial value table (representing a parity check matrix) of LDPC codes having various code lengths N and coding rates r can be prepared in advance. The LDPC encoder 115 can perform LDPC encoding to LDPC codes of various code lengths N and coding rates r using a check matrix H generated from a check matrix initial value table prepared in advance.

  <Example of parity check matrix initial value table>

The parity check matrix initial value table includes, for example, an information matrix H _A (corresponding to a code length N of an LDPC code (LDPC code defined by the parity check matrix H) and an information length K corresponding to a coding rate r of the parity check matrix H. FIG. 10) is a table showing the position of one element for each 360 columns (parallel factor P), and is created in advance for each check matrix H of each code length N and each coding rate r.

That is, the parity check matrix initial value table represents at least the position of one element of the information matrix _HA for every 360 columns (parallel factor P).

The parity check matrix H includes a parity check matrix in which all of the parity matrix H _T has a staircase structure, and a part of the parity matrix H _T has a staircase structure, and the remaining part is a diagonal matrix (unit matrix). There is a parity check matrix.

Hereinafter, a part of the parity matrix H _T has a staircase structure, the representation method of the parity check matrix initial value table represents the check matrix the rest becomes a diagonal matrix, also referred to as Type A system. Also, all of the parity matrix H _T is an expression scheme of the parity check matrix initial value table representative of the parity check matrix having a staircase structure, also referred to as type B method.

  An LDPC code for a parity check matrix represented by a type A parity check matrix initial value table is also referred to as a type A code, and an LDPC code for a parity check matrix represented by a type B parity check matrix initial value table is also referred to as a type B code.

  The names “type A” and “type B” are names according to the ATSC 3.0 standard. For example, in ATSC 3.0, both type A code and type B code are adopted.

  In DVB-T.2 etc., type B code is adopted.

  FIG. 20 is a diagram illustrating an example of a parity check matrix initial value table of a type B method.

  That is, FIG. 20 shows that the code length N is 16200 bits and the coding rate (coding rate in the notation of DVB-T.2) r is 1/4 as defined in the DVB-T.2 standard. The check matrix initial value table (representing the check matrix H) of the type B code is shown.

  The parity check matrix generation unit 613 (FIG. 18) obtains the parity check matrix H as follows using the Type B parity check matrix initial value table.

  FIG. 21 is a diagram for explaining a method for obtaining the parity check matrix H from the type B parity check matrix initial value table.

  That is, FIG. 21 illustrates a parity check matrix initial value table of a type B code defined in the DVB-T.2 standard and having a code length N of 16200 bits and an encoding rate r of 2/3.

The type B parity check matrix initial value table includes 360 columns (parallel factor) of the position of one element of the information matrix H _A corresponding to the information length K corresponding to the code length N and coding rate r of the LDPC code. P), and the i-th row contains the row number of the 1st element of the 1 + 360 × (i-1) column of the parity check matrix H (the row number of the first row of the parity check matrix H). (The row number set to 0) is arranged by the number of column weights of the 1 + 360 × (i−1) th column.

Here, since the parity matrix H _T (FIG. 10) corresponding to the parity length M of the parity check matrix H of the type B scheme is determined in a staircase structure as shown in FIG. 15, the parity check matrix initial value table If the information matrix H _A (FIG. 10) corresponding to the information length K can be obtained, the check matrix H can be obtained.

  The number of rows k + 1 in the type B check matrix initial value table differs depending on the information length K.

  The relationship of Expression (9) is established between the information length K and the number of rows k + 1 in the parity check matrix initial value table.

K = (k + 1) x 360
... (9)

  Here, 360 in Equation (9) is the parallel factor P described in FIG.

  In the parity check matrix initial value table of FIG. 21, 13 numerical values are arranged from the first line to the third line, and three values are arranged from the fourth line to the k + 1th line (the 30th line in FIG. 21). Are lined up.

  Therefore, the column weights of the parity check matrix H obtained from the parity check matrix initial value table of FIG. 21 are 13 from the first column to the 1 + 360 × (3-1) −1 column, and 1 + 360 × (3-1) It is 3 from the column to the Kth column.

  The first row of the parity check matrix initial value table in FIG. 21 is 0,2084,1613,1548,1286,1460,3196,4297,2481,3369,3451,4620,2622, which is the parity check matrix H In the first column, the row number is 0,2084,1613,1548,1286,1460,3196,4297,2481,3369,3451,4620,2622, and the element of the row is 1 (and other elements) Is 0).

  The second row of the parity check matrix initial value table in FIG. 21 is 1,122,1516,3448,2880,1407,1847,3799,3529,373,971,4358,3108, which is 361 of the parity check matrix H. In the (= 1 + 360 × (2-1)) column, the row number is 1,122,1516,3448,2880,1407,1847,3799,3529,373,971,4358,3108, indicating that the element is 1 ing.

As described above, the parity check matrix initial value table represents the position of one element of the information matrix _HA of the parity check matrix H for every 360 columns.

  Columns other than the 1 + 360 × (i-1) -th column of the parity check matrix H, that is, each column from the 2 + 360 × (i-1) -th column to the 360 × i-th column is a parity check matrix initial value table. The 1 element in the 1 + 360 × (i−1) column determined by ## EQU1 ## is arranged cyclically shifted downward (in the column downward direction) in accordance with the parity length M.

  That is, for example, the 2 + 360 × (i-1) column is a cyclic shift of the 1 + 360 × (i-1) column by M / 360 (= q) downward. The next 3 + 360 × (i-1) column is the 1 + 360 × (i-1) column cyclically shifted downward by 2 × M / 360 (= 2 × q) ( 2 + 360 × (i-1) column is cyclically shifted downward by M / 360 (= q)).

The numerical value of the i-th row (i-th from the top) and j-th column (j-th from the left) of the parity check matrix initial value table is represented as h _{i, j} and j items in the w-th column of the parity check matrix H. If the row number of the first element is represented as H _wj , the row number H of the first element in the w column, which is a column other than the 1 + 360 × (i−1) column of the parity check matrix H _wj can be obtained by Expression (10).

H _wj = mod {h _{i, j} + mod ((w-1), P) × q, M)
(10)

  Here, mod (x, y) means a remainder obtained by dividing x by y.

  P is the parallel factor described above, and is 360 in the present embodiment, for example, as in the DVB-T.2 and ATSC3.0 standards. Further, q is a value M / 360 obtained by dividing the parity length M by the parallel factor P (= 360).

  The parity check matrix generation unit 613 (FIG. 18) identifies the row number of the 1 element in the 1 + 360 × (i−1) column of the parity check matrix H using the parity check matrix initial value table.

Further, the parity check matrix generation unit 613 (FIG. 18) _calculates the row number H _wj of the first element of the w-th column other than the 1 + 360 × (i−1) -th column of the parity check matrix H by the formula ( 10) to generate a parity check matrix H in which the element of the row number obtained as described above is 1.

  FIG. 22 is a diagram illustrating the structure of a type A check matrix H.

  A type A parity check matrix includes an A matrix, a B matrix, a C matrix, a D matrix, and a Z matrix.

  The A matrix is an upper left matrix of the parity check matrix H of M1 rows and K columns expressed by a predetermined value M1 and an LDPC code information length K = code length N × coding rate r.

  The B matrix is a matrix having a staircase structure adjacent to the right of the A matrix and having M1 rows and M1 columns.

  The C matrix is a matrix adjacent to the N-K-M1 row K + M1 column below the A matrix and the B matrix.

  The D matrix is an N-K-M1 row N-K-M1 column adjacent unit matrix to the right of the C matrix.

  The Z matrix is a zero matrix (0 matrix) adjacent to the right of the B matrix and having M1 rows and N-K-M1 columns.

  In the check matrix H of the type A method composed of the A matrix to the D matrix and the Z matrix as described above, a part of the A matrix and the C matrix constitutes an information matrix, a B matrix, The remaining part of the C matrix, the D matrix, and the Z matrix constitute a parity matrix.

  Note that since the B matrix is a staircase structure matrix and the D matrix is a unit matrix, part of the parity matrix of the type A check matrix H (part of the B matrix) has a staircase structure. The remaining part (D matrix part) is a diagonal matrix (unit matrix).

  The A matrix and the C matrix have a cyclic structure for each column (for example, 360 columns) of the parallel factor P, similar to the information matrix of the type B check matrix H, and the type A check matrix initial value table Represents the position of one element of the A matrix and the C matrix every 360 columns.

  Here, as described above, since part of the A matrix and the C matrix constitutes an information matrix, a type A check matrix that represents the position of one element of the A matrix and the C matrix for every 360 columns. It can be said that the initial value table represents at least the position of one element of the information matrix every 360 columns.

  In addition, since the type A check matrix initial value table indicates the position of 1 element of the A matrix and the C matrix for every 360 columns, the part of the check matrix (the remaining part of the C matrix) It can also be said that the position is represented every 360 columns.

  FIG. 23 is a diagram illustrating an example of a type A check matrix initial value table.

  That is, FIG. 23 illustrates an example of a parity check matrix initial value table representing a parity check matrix H having a code length N of 35 bits and an encoding rate r of 2/7.

  The parity check matrix initial value table of the type A method is a table that represents the position of one element of the A matrix and the C matrix for each parallel factor P. In the i-th row, 1 + P × ( i-1) The row number of the 1st element in the column (the row number where the row number of the first row of the check matrix H is 0) is the column of the 1 + P × (i-1) th column. The number of weights is lined up.

  Here, in order to simplify the description, it is assumed that the parallel factor P is, for example, 5.

  For the type A check matrix H, there are M1, M2, Q1, and Q2 as parameters.

  M1 (FIG. 22) is a parameter that determines the size of the B matrix, and takes a value that is a multiple of the parallel factor P. By adjusting M1, the performance of the LDPC code changes, and is adjusted to a predetermined value when the parity check matrix H is determined. Here, it is assumed that 15 which is three times the parallel factor P = 5 is adopted as M1.

  M2 (FIG. 22) takes a value M-M1 obtained by subtracting M1 from the parity length M.

  Here, since the information length K is N × r = 35 × 2/7 = 10 and the parity length M is NK = 35−10 = 25, M2 is M−M1 = 25−15 = 10 It becomes.

  Q1 is calculated according to the equation Q1 = M1 / P and represents the number of cyclic shifts (number of rows) in the A matrix.

  That is, columns other than the 1 + P × (i-1) column of the A matrix of the type A check matrix H, that is, from the 2 + P × (i-1) column to the P × i column. Each column is arranged by cyclically shifting 1 element of 1 + P × (i-1) column determined by the parity check matrix initial value table downward (downward column). Q1 represents the number of cyclic shifts in the A matrix.

  Q2 is obtained according to the equation Q2 = M2 / P and represents the shift number (number of rows) of cyclic shift in the C matrix.

  That is, columns other than the 1 + P × (i-1) column of the C matrix of the type A check matrix H, that is, from the 2 + P × (i-1) column to the P × i column. Each column is arranged by cyclically shifting 1 element of 1 + P × (i-1) column determined by the parity check matrix initial value table downward (downward column). Q2 represents the number of shifts of the cyclic shift in the C matrix.

  Here, Q1 is M1 / P = 15/5 = 3, and Q2 is M2 / P = 10/5 = 2.

  In the parity check matrix initial value table in FIG. 23, three numerical values are arranged in the first and second rows, and one numerical value is arranged in the third to fifth rows. For example, the column weights of the A matrix and C matrix portions of the parity check matrix H obtained from the parity check matrix initial value table of FIG. 23 are 10 = 5 × 2 columns from the 1 = 1 + 5 × (1-1) th column. Up to the eye is 3, and from 11 = 1 + 5 × (3-1) th column to 25 = 5 × 5th column is 1.

  That is, the first row of the parity check matrix initial value table of FIG. 23 is 2,6,18. This is because the row numbers of 2,6,18 in the first column of the parity check matrix H are as follows. The element is 1 (and the other elements are 0).

  Here, in this case, the A matrix (FIG. 22) is a matrix of 15 rows and 10 columns (M1 rows and K columns), and the C matrix (FIG. 22) is 10 rows and 25 columns (NK-M1 rows K + M1). Column of the check matrix H are rows of the A matrix, and rows of the check matrix H are row numbers 15 to 24 of the C matrix.

  Therefore, of the rows with row numbers 2, 6, and 18 (hereinafter referred to as rows # 2, # 6, and # 18), rows # 2 and # 6 are rows of the A matrix, and rows # 18 is the C matrix row.

  The second row of the parity check matrix initial value table in FIG. 23 is 2,10,19, which is the row # 6 in the parity check matrix H (= 1 + 5 × (2-1)) column. This indicates that the elements # 2, # 10, and # 19 are 1.

  Here, in the sixth (= 1 + 5 × (2-1)) column of the check matrix H, the rows # 2, # 10 of the rows # 2, # 10, # 19 are rows of the A matrix. Yes, row # 19 is a row of the C matrix.

  The third row of the parity check matrix initial value table in FIG. 23 is 22, which means that in the 11th (= 1 + 5 × (3-1)) column of the parity check matrix H, the element of row # 22 is 1 is shown.

  Here, in the 11th (= 1 + 5 × (3-1)) column of parity check matrix H, row # 22 is a row of the C matrix.

  Similarly, 19 in the fourth row of the parity check matrix initial value table in FIG. 23 has 1 in row # 19 in the 16th (= 1 + 5 × (4-1)) column of parity check matrix H. 23 in the fifth row of the parity check matrix initial value table in FIG. 23, the element in row # 15 is 1 in the 21st (= 1 + 5 × (5-1)) column of the parity check matrix H. It is shown that.

  As described above, the parity check matrix initial value table represents the position of one element of the A matrix and the C matrix of the parity check matrix H for each parallel factor P = 5 columns.

  Columns other than the 1 + 5 × (i-1) column of the A matrix and C matrix of the check matrix H, that is, each column from the 2 + 5 × (i-1) column to the 5 × i column is The 1 element in the 1 + 5 × (i-1) column determined by the parity check matrix initial value table is cyclically shifted in the downward direction (downward direction of the column) according to the parameters Q1 and Q2. It is a thing.

  That is, for example, the 2 + 5 × (i-1) column of the A matrix is the 1 + 5 × (i-1) column cyclically shifted downward by Q1 (= 3). The next 3 + 5 × (i-1) column is the 1 + 5 × (i-1) column cyclically shifted downward by 2 × Q1 (= 2 × 3) ( The 2 + 5 × (i-1) column is cyclically shifted downward by Q1).

  Also, for example, the 2 + 5 × (i-1) column of the C matrix is a cyclic shift of the 1 + 5 × (i-1) column downward by Q2 (= 2). The next 3 + 5 × (i-1) column is the 1 + 5 × (i-1) column cyclically shifted downward by 2 × Q2 (= 2 × 2) ( 2 + 5 × (i-1) column is cyclically shifted downward by Q2).

  FIG. 24 is a diagram illustrating an A matrix generated from the parity check matrix initial value table of FIG.

  In the A matrix in FIG. 24, the elements in the rows # 2 and # 6 in the 1 (= 1 + 5 × (1-1)) column are 1 according to the first row of the parity check matrix initial value table in FIG. ing.

  And each column from the 2 (= 2 + 5 × (1-1)) column to the 5 (= 5 + 5 × (1-1)) column is down the previous column by Q1 = 3 It has become a cyclic shift.

  Furthermore, in the matrix A in FIG. 24, the elements in the rows # 2 and # 10 in the 6 (= 1 + 5 × (2-1)) column are 1 according to the second row of the parity check matrix initial value table in FIG. It has become.

  And each column from the 7 (= 2 + 5 × (2-1)) column to the 10 (= 5 + 5 × (2-1)) column is down the previous column by Q1 = 3 It has become a cyclic shift.

  FIG. 25 is a diagram illustrating parity interleaving of the B matrix.

  The parity check matrix generation unit 613 (FIG. 18) generates a matrix A using the parity check matrix initial value table, and arranges a matrix B having a staircase structure on the right side of the matrix A. Then, parity check matrix generation section 613 regards B matrix as a parity matrix, and performs parity interleaving so that adjacent one element of B matrix having a staircase structure is separated by a parallel factor P = 5 in the row direction.

  FIG. 25 shows the A matrix and the B matrix after parity interleaving of the B matrix of FIG.

  FIG. 26 is a diagram illustrating a C matrix generated from the parity check matrix initial value table of FIG.

  In the C matrix of FIG. 26, the element in row # 18 of the 1 (= 1 + 5 × (1-1)) column of the check matrix H is set to 1 according to the first row of the parity check matrix initial value table of FIG. It has become.

  And each column from the 2 (= 2 + 5 × (1-1)) column to the 5 (= 5 + 5 × (1-1)) column of the C matrix is the previous column, Q2 = 2 It's just a cyclic shift down.

  Further, in the C matrix of FIG. 26, the 6th (= 1 + 5 × (2-1)) column row # of the parity check matrix H in accordance with the second to fifth rows of the parity check matrix initial value table of FIG. 19 and 11 (= 1 + 5 × (3-1)) column # 22, 16 (= 1 + 5 × (4-1)) column # 19 and 21 (= 1 + 5) The element in row # 15 of the (× (5-1)) column is 1.

  And each column from column 7 (= 2 + 5 × (2-1)) to column 10 (= 5 + 5 × (2-1)), 12 (= 2 + 5 × (3-1) ) To 15 (= 5 + 5 × (3-1)), 17 (= 2 + 5 × (4-1)) to 20 (= 5 + 5 × (4- 1)) Each column up to column 22 and each column from column 22 (= 2 + 5 × (5-1)) to column 25 (= 5 + 5 × (5-1)) This column is cyclically shifted downward by Q2 = 2.

  The parity check matrix generation unit 613 (FIG. 18) generates a C matrix using the parity check matrix initial value table, and arranges the C matrix below the A matrix and the B matrix (after parity interleaving).

  Further, parity check matrix generation section 613 arranges a Z matrix on the right side of B matrix and arranges a D matrix on the right side of C matrix to generate parity check matrix H shown in FIG.

  FIG. 27 is a diagram illustrating parity interleaving of the D matrix.

  After generating the check matrix H of FIG. 26, the check matrix generation unit 613 regards the D matrix as a parity matrix, and 1 element of the odd-numbered row and the next even-numbered row of the unit matrix is arranged in the row direction. Parity interleaving (of D matrix only) is performed so that the parallel factor P = 5.

  FIG. 27 illustrates the parity check matrix H after parity interleaving of the D matrix for the parity check matrix H in FIG.

  The LDPC encoder 115 (the encoded parity calculation unit 615 (FIG. 18)) performs LDPC encoding (generation of an LDPC code) using, for example, the parity check matrix H of FIG.

  Here, the LDPC code generated using the parity check matrix H of FIG. 27 is an LDPC code subjected to parity interleaving. Therefore, the LDPC code generated using the parity check matrix H of FIG. It is not necessary to perform parity interleaving in the parity interleaver 23 (FIG. 9). That is, since the LDPC code generated using the parity check matrix H after the parity interleaving of the D matrix is the LDPC code subjected to the parity interleaving, the parity interleaving in the parity interleaver 23 is performed for the LDPC code. Is skipped.

  FIG. 28 returns the parity interleaving to the B matrix of the parity check matrix H of FIG. 27, a part of the C matrix (the part of the C matrix arranged below the B matrix), and the D matrix. It is a figure which shows the check matrix H which performed the column permutation (column permutation) as a parity deinterleaving.

  LDPC encoder 115 can perform LDPC encoding (generation of an LDPC code) using parity check matrix H in FIG.

  When performing LDPC coding using parity check matrix H in FIG. 28, according to the LDPC coding, an LDPC code not subjected to parity interleaving can be obtained. Therefore, when performing LDPC encoding using parity check matrix H in FIG. 28, parity interleaving is performed in parity interleaver 23 (FIG. 9).

  FIG. 29 is a diagram illustrating a transformed parity check matrix H obtained by performing row permutation on the parity check matrix H of FIG.

  As will be described later, the conversion parity check matrix is a P × P unit matrix, a quasi-unit matrix in which one or more of the unit matrices become 0, a shift matrix obtained by cyclically shifting the unit matrix or the quasi-unit matrix, It is a matrix represented by a combination of a sum matrix that is a sum of two or more of a unit matrix, a quasi-unit matrix, or a shift matrix, and a P × P 0 matrix.

  By using the transform check matrix for decoding the LDPC code, it is possible to employ an architecture that simultaneously performs P check node operations and variable node operations in the decoding of the LDPC code, as will be described later.

  <New LDPC code>

  In data transmission using an LDPC code, one method of ensuring good communication quality is a method using an LDPC code with good performance.

  Hereinafter, a new LDPC code with good performance (hereinafter also referred to as a new LDPC code) will be described.

  As a new LDPC code, for example, a parallel factor P is 360, which is the same as DVB-T.2 or ATSC 3.0, and a type A code or a type B code corresponding to a check matrix H of a cyclic structure may be adopted. it can.

  The LDPC encoder 115 (FIGS. 8 and 18) has a code length N longer than 64k bits, for example, 69120 bits, and a coding rate r of, for example, 2/16, 3/16, 4/16, 5/16, 6/16, 7/16, 8/16, 9/16, 10/16, 11/16, 12/16, 13/16, or 14/16 LDPC encoding to the new LDPC code can be performed using the parity check matrix initial value table of the new LDPC code (check matrix H obtained from the above).

  In this case, a check matrix initial value table of the new LDPC code is stored in storage unit 602 of LDPC encoder 115 (FIG. 8).

  FIG. 30 shows a parity check matrix H of a type A code (hereinafter also referred to as a type A code of r = 2/16) as a new LDPC code having a code length N of 69120 bits and a coding rate r of 2/16. It is a figure which shows the example of a check matrix initial value table (of a type A system).

  31 and 32 show a type A code (hereinafter also referred to as a type A code of r = 3/16) as a new LDPC code having a code length N of 69120 bits and a coding rate r of 3/16. 6 is a diagram illustrating an example of a parity check matrix initial value table representing a parity check matrix H.

  The new LDPC code is a high-performance LDPC code.

  Here, a high-performance LDPC code is an LDPC code obtained from an appropriate parity check matrix H.

An appropriate check matrix H is, for example, when an LDPC code obtained from the check matrix H is transmitted at a low E _s / N ₀ or E _b / N _o (signal power to noise power ratio per bit). , BER (bit error rate) (and FER (frame error rate)) is a check matrix that satisfies a predetermined condition.

An appropriate parity check matrix H can be obtained, for example, by performing a simulation for measuring the BER when LDPC codes obtained from various parity check matrices satisfying a predetermined condition are transmitted at low E _s / N _o .

  The predetermined conditions that the appropriate check matrix H should satisfy are, for example, that the analysis result obtained by the code performance analysis method called Density Evolution is good, and that one element called cycle 4 There are no loops, etc.

Here, in the information matrix H _A , it is known that the decoding performance of the LDPC code is deteriorated when one element is dense as in the cycle 4. It is desirable that 4 does not exist.

  In the parity check matrix H, the minimum value of the loop length (loop length) constituted by one element is called girth. The absence of cycle 4 means that the girth is greater than 4.

  Note that the predetermined condition to be satisfied by an appropriate parity check matrix H can be appropriately determined from the viewpoint of improving the decoding performance of the LDPC code, facilitating (simplifying) the decoding process of the LDPC code, and the like.

  FIG. 86 and FIG. 87 are diagrams for explaining density evolution in which an analysis result is obtained as a predetermined condition that should be satisfied by an appropriate check matrix H.

  Density evolution is a code analysis method that calculates the expected value of the error probability for the entire LDPC code (ensemble) whose code length N is ∞ characterized by the degree sequence described later. It is.

  For example, on an AWGN channel, when the noise variance is increased from 0, the expected value of the error probability of a certain ensemble is initially 0, but the noise variance is greater than a certain threshold. Then, it is not 0.

  According to Density Evolution, the expected value of the error probability is not zero, and the threshold of noise variance (hereinafter also referred to as performance threshold) is compared to determine whether the ensemble performance (appropriateness of the check matrix) is good or bad. Can be decided.

  Note that if a specific LDPC code is assigned with an ensemble to which the LDPC code belongs, and density evolution is performed on the ensemble, the rough performance of the LDPC code can be predicted.

  Accordingly, if an LDPC code having good performance is found, an ensemble having good performance can be found from among LDPC codes belonging to the ensemble.

  Here, the above-described degree sequence represents the proportion of variable nodes and check nodes each having a weight of each value with respect to the code length N of the LDPC code.

  For example, a regular (3,6) LDPC code with a coding rate of 1/2 is a degree in which the weights (column weights) of all variable nodes are 3 and the weights (row weights) of all check nodes are 6. Belongs to an ensemble characterized by a sequence.

  FIG. 86 shows a Tanner graph of such an ensemble.

  In the Tanner Bluff of FIG. 86, there are only N variable nodes indicated by circles (circles) in the figure, which are equal to the code length N, and check nodes indicated by squares (□ marks) in the figure are coded at the code length N. There are only N / 2 equal to the product of multiplication by 1/2.

  Each variable node is connected with three edges equal to the column weight. Therefore, there are only 3N branches connected to the N variable nodes.

  Each check node is connected with 6 branches equal to the row weight. Therefore, there are only 3N branches connected to N / 2 check nodes.

  Further, in the Tanner graph of FIG. 86, there is one interleaver.

  The interleaver randomly reorders 3N branches connected to N variable nodes, and reorders each of the rearranged branches into 3N branches connected to N / 2 check nodes. Connect to one of them.

  There are (3N)! (= (3N) × (3N-1) × ... × 1) rearrangement patterns for rearranging 3N branches connected to N variable nodes in the interleaver. There are only. Therefore, an ensemble characterized by a degree sequence where all variable nodes have a weight of 3 and all check nodes have a weight of 6 is a set of (3N)! LDPC codes.

  In the simulation for obtaining a high-performance LDPC code (appropriate parity check matrix), a multi-edge type ensemble was used in the density evolution.

  In the multi-edge type, the interleaver through which the branch connected to the variable node and the branch connected to the check node pass is divided into multiple edges, which makes the ensemble more characterized. Strictly done.

  FIG. 87 shows an example of a Tanner graph of a multi-edge type ensemble.

  In the Tanner graph of FIG. 87, there are two interleavers, a first interleaver and a second interleaver.

  In the Tanner graph of FIG. 87, there is one branch connected to the first interleaver, only one v1 variable node having zero branches connected to the second interleaver, and one branch connected to the first interleaver. , There are only 2 variable nodes with 2 branches connected to the second interleaver, 0 branches with the 1st interleaver, v3 branches with 2 branches connected to the 2nd interleaver, Exists.

  Furthermore, in the Tanner graph of FIG. 87, there are 2 branches connected to the first interleaver, 0 branches connected to the second interleaver, only c1 check nodes, and 2 branches connected to the first interleaver. The number of branches connected to the second interleaver is c2 check nodes, the number of branches connected to the first interleaver is 0, and the number of branches connected to the second interleaver is c3. Exists.

  Here, for density evolution and its implementation, for example, "On the Design of Low-Density Parity-Check Codes within 0.0045 dB of the Shannon Limit", SYChung, GDForney, TJRichardson, R.Urbanke, IEEE Communications Leggers, VOL.5, NO.2, Feb 2001.

In the simulation for obtaining a new LDPC code (its check matrix), BER starts to decrease (becomes smaller) due to multi-edge type density evolution, which is E _b / N ₀ (signal power to noise power ratio per bit). Find an ensemble whose performance threshold is less than or equal to a predetermined value, and select an LDPC code that reduces the BER when using one or more orthogonal modulations such as QPSK from among the LDPC codes that belong to the ensemble. Selected.

  The new LDPC code (the parity check matrix initial value table representing the parity check matrix) was obtained by the above simulation.

  Therefore, according to the new LDPC code, good communication quality can be ensured in data transmission.

  FIG. 88 is a diagram for explaining column weights of a parity check matrix H of a type A code as a new LDPC code.

  For the check matrix H of type A code, as shown in FIG. 88, the column weight of the K1 column from the first column of the A matrix is Y1, the column weight of the subsequent K2 column of the A matrix is Y2, and the C matrix The column weight of the K1 column from the first column is represented as X1, the column weight of the subsequent K2 column of the C matrix as X2, and the column weight of the M1 column after the C matrix as X3.

  K1 + K2 is equal to the information length K, and M1 + M2 is equal to the parity length M. Therefore, K1 + K2 + M1 + M2 is equal to the code length N = 69120 bits.

  For the check matrix H of type A code, the column weights from the first column to the M1-1 column of the B matrix are 2, and the column weight of the M1 column (last column) of the B matrix is 1. Further, the column weight of the D matrix is 1, and the column weight of the Z matrix is 0.

  The parameters X1, Y1, K1 (or K2), X2, Y2, X3, and M1 (or M2) are set so that the performance (for example, error rate) of the LDPC code is further improved.

  FIG. 90 is a diagram for explaining column weights of a check matrix H of a type B code as a new LDPC code.

  For the parity check matrix H of the type B code, as shown in FIG. 90, the column weight of the KX1 column from the first column is X1, the column weight of the subsequent KX2 column is X2, and the column weight of the subsequent KY1 column is Y1. And the column weight of the subsequent KY2 column is represented as Y2.

  KX1 + KX2 + KY1 + KY2 is equal to the information length K, and KX1 + KX2 + KY1 + KY2 + M is equal to the code length N = 69120 bits.

  In addition, for the parity check matrix H of the type B code, the column weight of the M−1 column excluding the last one of the last M columns is 2, and the column weight of the last one column is 1.

  FIG. 91 is a diagram illustrating parameters of the parity check matrix H of the type B code (represented by the parity check matrix initial value table) in FIGS. 42 to 85.

  <Constellation>

  98 to 122 are diagrams showing examples of constellations that can be employed in the transmission system of FIG.

  In the transmission system of FIG. 7, for example, a constellation used in the MODCOD can be set for MODCOD which is a combination of a modulation scheme (MODulation) and an LDPC code (CODe).

  One or more constellations can be set for one MODCOD.

  Constellation includes UC (Uniform Constellation) in which signal points are uniformly arranged and NUC (Non Uniform Constellation) in which signal points are not uniformly arranged.

NUC includes, for example, a constellation called 1D-NUC (1-dimensional (M ² -QAM) non-uniform constellation) and a constellation called 2D-NUC (2-dimensional (QQAM) non-uniform constellation). There is a management.

  In general, BER improves with 1D-NUC over UC, and further, BER improves with 2D-NUC over 1D-NUC.

  The constellation whose modulation method is QPSK is UC. For example, UC or 2D-NUC can be used as the constellation such as 16QAM, 64QAM, or 256QAM, and the constellation such as 1024QAM or 4096QAM is used as the constellation such as UC or 1D. -NUC can be adopted.

  In the transmission system of FIG. 7, for example, constellations defined by ATSC 3.0, DVB-C.2, etc., and various other constellations that improve the error rate can be used.

  That is, when the modulation scheme is QPSK, for example, the same UC can be used for each coding rate r of the LDPC code.

  Further, when the modulation scheme is 16QAM, 64QAM, or 256QAM, for example, the same UC can be used for each coding rate r of the LDPC code. Furthermore, when the modulation scheme is 16QAM, 64QAM, or 256QAM, for example, a different 2D-NUC can be used for each coding rate r of the LDPC code.

  When the modulation scheme is 1024QAM or 4096QAM, for example, the same UC can be used for each coding rate r of the LDPC code. Furthermore, when the modulation scheme is 1024QAM or 4096QAM, for example, a different 1D-NUC can be used for each coding rate r of the LDPC code.

Here, the UC of QPSK, described with QPSK-UC, the UC of 2 ^m QAM, also referred to as 2 ^m QAM-UC. Also, 2 ^m QAM 1D-NUC and 2D-NUC are also referred to as 2 ^m QAM-1D-NUC and 2 ^m QAM-2D-NUC, respectively.

  The following describes some of the constellations defined in ATSC 3.0.

  FIG. 98 is a diagram illustrating the coordinates of QPSK-UC signal points used for all coding rates of LDPC codes defined in ATSC 3.0 when the modulation scheme is QPSK.

In FIG. 98, “Input Data cell y” represents a 2-bit symbol mapped to QPSK-UC, and “Constellation point z _s ” represents the coordinates of the signal point z _s . The index s of the signal point z _s (the same applies to the index q of the signal point z _q described later) represents the discrete time of the symbol (time interval between one symbol and the next symbol).

In FIG. 98, the coordinates of the signal point z _s are represented in the form of complex numbers, and j represents an imaginary unit (√ (−1)).

  FIG. 99 shows the coding rate r (CR) of LDPC code defined by ATSC 3.0 when the modulation method is 16QAM = 2/15, 3/15, 4/15, 5/15, 6 / It is a figure which shows the coordinate of the signal point of 16QAM-2D-NUC used about 15, 7/15, 8/15, 9/15, 10/15, 11/15, 12, 15, 13/15.

In FIG. 99, as in FIG. 98, the coordinates of the signal point z _s are represented in the form of complex numbers, and j represents an imaginary unit.

  In FIG. 99, w # k represents the coordinates of signal points in the first quadrant of the constellation.

  In 2D-NUC, the signal points in the second quadrant of the constellation are arranged at positions shifted symmetrically with respect to the Q axis in the first quadrant, and the signal points in the third quadrant of the constellation are A signal point in one quadrant is arranged at a position moved symmetrically with respect to the origin. The signal points in the fourth quadrant of the constellation are arranged at positions where the signal points in the first quadrant are moved symmetrically with respect to the I axis.

Here, when the modulation method is 2 ^m QAM, m bits are regarded as one symbol, and the one symbol is mapped to a signal point corresponding to the symbol.

For example, an m-bit symbol can be represented by an integer value of 0 to 2 ^m −1. However, if b = 2 ^m / 4, it is represented by an integer value of 0 to 2 ^m −1. y (0), y (1), ..., y (2 ^m -1) are symbols y (0) to y (b-1), y (b) to y (2b-1), y ( 2b) to y (3b-1) and y (3b) to y (4b-1).

  In FIG. 99, the suffix k of w # k takes an integer value ranging from 0 to b-1, and w # k represents the symbol y (k) ranging from symbol y (0) to y (b-1). Represents the coordinates of the signal point corresponding to.

  The coordinates of the signal point corresponding to the symbol y (k + b) in the range of the symbols y (b) to y (2b-1) are represented by -conj (w # k), and the symbols y (2b) to The coordinates of the signal point corresponding to the symbol y (k + 2b) in the range of y (3b-1) are represented by conj (w # k). Further, the coordinates of the signal point corresponding to the symbol y (k + 3b) in the range of the symbols y (3b) to y (4b-1) are represented by -w # k.

  Here, conj (w # k) represents the complex conjugate of w # k.

For example, when the modulation scheme is 16QAM, the m = 4 bits of the symbol y (0), y (1 ), ···, y (15) as ^{b = 2 4/4 = 4} , the symbols y There are four categories: (0) to y (3), y (4) to y (7), y (8) to y (11), and y (12) to y (15).

  Of the symbols y (0) to y (15), for example, the symbol y (12) is a symbol y (k + 3b) = y (in the range of symbols y (3b) to y (4b-1). Since 0 + 3 × 4) and k = 0, the coordinates of the signal point corresponding to the symbol y (12) are −w # k = −w0.

  Now, assuming that the coding rate r (CR) of the LDPC code is 9/15, for example, according to FIG. 99, w0 when the modulation scheme is 16QAM and the coding rate r is 9/15. Is 0.2386 + j0.5296, the coordinates -w0 of the signal point corresponding to the symbol y (12) is-(0.2386 + j0.5296).

  FIG. 100 shows an LDPC code coding rate r (CR) stipulated by ATSC 3.0 = 2/15, 3/15, 4/15, 5/15, 6 / when the modulation method is 1024QAM. It is a figure which shows the example of the coordinate of the signal point of 1024QAM-1D-NUC used about 15, 7/15, 8/15, 9/15, 10/15, 11/15, 12, 15, 13/15 .

In FIG. 100, u # k represents a complex real part Re (z _s ) and an imaginary part Im (z _s ) as coordinates of a signal point z _s of 1D-NUC, and a vector u = (u0) called a position vector , u1, ..., u # V-1). The number V of components u # k of the position vector u is given by the equation V = √ (2 ^m ) / 2.

  FIG. 101 is a diagram illustrating a relationship between a 1024QAM symbol y and a position vector u (component u # k thereof).

Now, the 10-bit symbol y of 1024QAM is changed from the first bit (most significant bit) to y _{0, s} , y _{1, s} , y _{2, s} , y _{3, s} , y _{4, s} , y _{5, s} , y6 _{, s} , y7 _{, s} , y8 _{, s} , y9 _{, s} .

101A shows an even-numbered five bits y _{1, s} , y _{3, s} , y _{5, s} , y _{7, s} , y _{9, s} of the symbol y and a signal point z _s corresponding to the symbol y. This represents a correspondence relationship with u # k representing the real part Re (z _s ).

B in FIG. 101 shows odd-numbered five bits y _{0, s} , y _{2, s} , y _{4, s} , y _{6, s} , y _{8, s} of the symbol y and a signal point z _s corresponding to the symbol y. This represents the correspondence with u # k representing the imaginary part Im (z _s ).

1024QAM 10-bit symbol y = (y _{0, s} , y _{1, s} , y _{2, s} , y _{3, s} , y _{4, s} , y _{5, s} , y _{6, s} , y _{7, s} , y _{8, s} , y _{9, s} ) is, for example, (0,0,1,0,0,1,1,1,0,0), the odd-numbered 5 bits (y _{0, s} , y _{2, s} , y _{4, s} , y _{6, s} , y _{8, s} ) is (0,1,0,1,0) and the even-numbered 5 bits (y _{1, s} , y _{3, s} , Y _{5, s} , y _{7, s} , y _{9, s} ) is (0,0,1,1,0).

In FIG. 101A, even-numbered 5 bits (0,0,1,1,0) are associated with u11, and therefore the symbol y = (0,0,1,0,0,1, The real part Re (z _s ) of the signal point z _s corresponding to 1,1,0,0) is u11.

In FIG. 101B, the odd-numbered 5 bits (0,1,0,1,0) are associated with u3, and therefore the symbol y = (0,0,1,0,0,1, The imaginary part Im (z _s ) of the signal point z _s corresponding to 1,1,0,0) is u3.

  On the other hand, if the coding rate r of the LDPC code is 6/15, for example, according to FIG. 100 described above, the modulation scheme is 1024QAM, and the coding rate r (CR) of the LDPC code is 6/15. For 1D-NUC used in some cases, u3 is 0.1295 and u11 is 0.7196.

Therefore, the real part Re (z _s ) of the signal point z _s corresponding to the symbol y = (0,0,1,0,0,1,1,1,0,0) is u11 = 0.7196, and the imaginary Part Im (z _s ) becomes u3 = 0.1295. As a result, the coordinates of the signal point z _s corresponding to the symbol y = (0,0,1,0,0,1,1,1,0,0) are represented by 0.7196 + j0.1295.

Note that 1D-NUC signal points are arranged in a lattice pattern on a straight line parallel to the I axis and a straight line parallel to the Q axis in the constellation. However, the interval between signal points is not constant. Further, when transmitting signal points (data mapped to), the average power of signal points on the constellation can be normalized.

  <Block interleaver 25>

  FIG. 123 is a diagram illustrating block interleaving performed by the block interleaver 25 in FIG.

  Block interleaving is performed by dividing an LDPC code of one codeword into a part called part 1 (part 1) and a part called part 2 (part 2) from the head.

  If the length (number of bits) of part 1 represents Npart1 and the length of part 2 is represented as Npart2, Npart1 + Npart2 is equal to the code length N.

  Conceptually, in block interleaving, the column as a storage area for storing Npart1 / m bits in the column (vertical) direction as one direction, the number of symbol bits in the row direction orthogonal to the column direction A number m equal to m is arranged, and each column is divided from the top into 360-bit small units having a parallel factor P. This small unit of column is also referred to as a column unit.

  In block interleaving, as shown in FIG. 123, part 1 of an LDPC code of one codeword is written from the top to the bottom (column direction) of the first column unit of the column. Done towards.

  When the writing to the first column unit of the rightmost column ends, as shown in FIG. 123, returning to the leftmost column, writing from the top to the bottom of the second column unit of the column can be performed from the left. The writing is performed toward the column in the right direction, and thereafter, the writing of part 1 of the LDPC code of one codeword is performed in the same manner.

  When the writing of part 1 of the LDPC code of one code word is completed, as shown in FIG. 123, part 1 of the LDPC code is read in m-bit units in the row direction from the first row of all m columns. .

  The m-bit unit of Part 1 is supplied from the block interleaver 25 to the mapper 117 (FIG. 8) as an m-bit symbol.

  Reading part 1 in m-bit units is performed sequentially toward the bottom row of m columns, and when reading of part 1 is completed, part 2 is divided into m-bit units from the beginning, and m bits Are supplied from the block interleaver 25 to the mapper 117.

  Therefore, part 1 is symbolized while being interleaved, and part 2 is symbolized by sequentially dividing into m bits without being interleaved.

  The length of the column, Npart1 / m, is a multiple of 360, which is the parallel factor P, and the LDPC code of one codeword is part 1 and part 2 so that Npart1 / m is a multiple of 360. And divided.

  FIG. 124 is a diagram illustrating examples of Part 1 and Part 2 of an LDPC code having a code length N of 69120 bits when the modulation scheme is QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM.

  In FIG. 124, when the modulation scheme is 1024QAM, part 1 is 68400 bits, part 2 is 720 bits, and the modulation scheme is QPSK, 16QAM, 64QAM, 256QAM, or 4096QAM. In this case, part 1 is 69120 bits and part 2 is 0 bits.

  <Groupwise Interleave>

  FIG. 125 is a diagram for explaining group-wise interleaving performed by the group-wise interleaver 24 of FIG.

  In group-wise interleaving, as shown in FIG. 125, an LDPC code of one code word is divided into 360 bit units equal to the parallel factor P from the head, and one bit of 360 bits as one bit group is used as one code. The LDPC codes of words are interleaved according to a predetermined pattern (hereinafter also referred to as GW pattern) in bit group units.

  Here, the i + 1-th bit group from the beginning when the LDPC code of one codeword is divided into bit groups is also referred to as bit group i hereinafter.

  When the parallel factor P is 360, for example, an LDPC code having a code length N of 1800 bits is divided into 5 (= 1800/360) bit groups of bit groups 0, 1, 2, 3, and 4. Further, for example, an LDPC code having a code length N of 69120 bits is divided into 192 (= 69120/360) bit groups of bit groups 0, 1,.

  In the following, the GW pattern is represented by a sequence of numbers representing bit groups. For example, for an LDPC code of 5 bit groups 0, 1, 2, 3, and 4 having a code length N of 1800 bits, for example, GW pattern 4, 2, 0, 3, 1 This indicates that the sequence of 2, 3 and 4 is interleaved (rearranged) in the order of bit groups 4, 2, 0, 3, and 1.

For example, suppose that the i + 1-th code bit from the beginning of an LDPC code having a code length N of 1800 bits is represented by x _i .

In this case, according to the group-wise interleaving of the GW patterns 4, ₂ , ₀ , ₃ , ₁ , ₁ , the 1800-bit LDPC code {x ₀ , x ₁ , ..., x ₁₇₉₉ } is represented by {x ₁₄₄₀ , x ₁₄₄₁ , ..., x ₁₇₉₉ }, {x ₇₂₀ , x ₇₂₁ , ..., x ₁₀₇₉ }, {x ₀ , x ₁ , ..., x ₃₅₉ }, {x ₁₀₈₀ , x ₁₀₈₁ , ..., x ₁₄₃₉ }, {x ₃₆₀ , x ₃₆₁ , ..., x ₇₁₉ } are interleaved.

  The GW pattern has two or more of the code length N of the LDPC code, the coding rate r, the modulation method, the constellation, and the code length N, the coding rate r, the modulation method, and the constellation. Can be set for each combination.

  The frame management unit 152 performs processing (frame interpretation) of a frame composed of data supplied from the OFDM processing unit 151, and converts the target data signal and the control data signal obtained as a result thereof into a frequency deinterleaver. (Frequency Deinterleaver) 161 and 153, respectively.

  The frequency deinterleaver 153 performs frequency deinterleaving on a symbol-by-symbol basis for the data from the frame management unit 152 and supplies the data to a demapper 154.

  The demapper 154 demaps the data (constellation data) from the frequency deinterleaver 153 based on the signal point arrangement (constellation) determined by the orthogonal modulation performed on the transmission device 11 side. The data (LDPC code (its likelihood)) obtained as a result is supplied to an LDPC decoder 155.

  The LDPC decoder 155 performs LDPC decoding of the LDPC code from the demapper 154, and supplies LDPC target data (here, BCH code) obtained as a result to a BCH decoder (BCH decoder) 156.

  The BCH decoder 156 performs BCH decoding of the LDPC target data from the LDPC decoder 155 and outputs control data (signaling) obtained as a result.

  On the other hand, the frequency deinterleaver 161 performs frequency deinterleaving on a symbol-by-symbol basis for the data from the frame management unit 152 and supplies the data to a SISO / MISO decoder 162.

  The SISO / MISO decoder 162 performs space-time decoding of the data from the frequency deinterleaver 161 and supplies it to a time deinterleaver 163.

  The time deinterleaver 163 performs time deinterleave on the data from the SISO / MISO decoder 162 in symbol units, and supplies the demapper 164 with it.

  The demapper 164 demaps the data (data on the constellation) from the time deinterleaver 163 based on the signal point arrangement (constellation) determined by the orthogonal modulation performed on the transmission device 11 side. The data obtained as a result is supplied to a bit deinterleaver 165.

  The bit deinterleaver 165 performs bit deinterleaving of the data from the demapper 164 and supplies the LDPC code (likelihood) that is the data after the bit deinterleaving to the LDPC decoder 166.

  The LDPC decoder 166 performs LDPC decoding of the LDPC code from the bit deinterleaver 165 and supplies LDPC target data (here, BCH code) obtained as a result to the BCH decoder 167.

  <Configuration Example of Bit Deinterleaver 165>

  FIG. 138 is a block diagram illustrating a configuration example of the bit deinterleaver 165 of FIG.

  The bit deinterleaver 165 includes a block deinterleaver 54 and a groupwise deinterleaver 55. The bit deinterleaver 165 performs (bit) deinterleaving of the symbol bits of the symbols that are data from the demapper 164 (FIG. 137).

  That is, the block deinterleaver 54 targets the symbol bit of the symbol from the demapper 164 and performs block deinterleave corresponding to the block interleave performed by the block interleaver 25 in FIG. Block deinterleaving is performed to return the position of the code bits (likelihood) of the LDPC codes rearranged by interleaving to the original position, and the resulting LDPC code is supplied to the group-wise deinterleaver 55.

  The group-wise deinterleaver 55 targets the LDPC code from the block deinterleaver 54 and performs group-wise deinterleave corresponding to the group-wise interleave performed by the group-wise interleaver 24 in FIG. 9 (inverse processing of group-wise interleave). That is, for example, by reordering the code bits of the LDPC code whose arrangement has been changed in units of bit groups by the groupwise interleaving described with reference to FIG. 125, groupwise deinterleaving to restore the original order is performed.

  Here, when parity interleaving, groupwise interleaving, and block interleaving are applied to the LDPC code supplied from the demapper 164 to the bit deinterleaver 165, the bit deinterleaver 165 uses the parity corresponding to the parity interleaving. Deinterleaving (reverse processing of parity interleaving, that is, parity deinterleaving for returning the code bits of the LDPC code whose sequence has been changed by parity interleaving), block deinterleaving corresponding to block interleaving, and groupwise interleaving All of the groupwise deinterleaves corresponding to can be performed.

  However, in the bit deinterleaver 165 of FIG. 138, the block deinterleaver 54 that performs block deinterleave corresponding to block interleave, and the groupwise deinterleaver 55 that performs groupwise deinterleave corresponding to groupwise interleave, Although provided, a block that performs parity deinterleaving corresponding to parity interleaving is not provided, and parity deinterleaving is not performed.

  Therefore, from the bit deinterleaver 165 (groupwise deinterleaver 55) to the LDPC decoder 166, an LDPC code subjected to block deinterleaving and groupwise deinterleaving and not subjected to parity deinterleaving. Is supplied.

  The LDPC decoder 166 performs LDPC decoding of the LDPC code from the bit deinterleaver 165, and column replacement corresponding to parity interleaving for the parity check matrix H of the type B scheme used by the LDPC encoder 115 in FIG. 8 for LDPC encoding. Is performed using a conversion parity check matrix obtained by performing row substitution on a type A parity check matrix (FIG. 27) and data obtained as a result of the LDPC target. Output as data decryption result.

  FIG. 139 is a flowchart for describing processing performed by the demapper 164, the bit deinterleaver 165, and the LDPC decoder 166 of FIG. 138.

  In step S111, the demapper 164 demaps and orthogonally demodulates the data from the time deinterleaver 163 (data on the constellation mapped to the signal points), supplies it to the bit deinterleaver 165, and performs the processing. The process proceeds to step S112.

  In step S112, the bit deinterleaver 165 performs deinterleaving (bit deinterleaving) of data from the demapper 164, and the process proceeds to step S113.

  That is, in step S112, in the bit deinterleaver 165, the block deinterleaver 54 performs block deinterleaving on the data (symbol) from the demapper 164, and the code bits of the LDPC code obtained as a result are grouped. Supplied to the wise deinterleaver 55.

  The groupwise deinterleaver 55 performs groupwise deinterleaving on the LDPC code from the block deinterleaver 54 and supplies the LDPC code (the likelihood) obtained as a result to the LDPC decoder 166.

  In step S113, the LDPC decoder 166 performs LDPC decoding of the LDPC code from the group-wise deinterleaver 55 using the parity check matrix H used by the LDPC encoder 115 of FIG. 8 for LDPC encoding. The conversion check matrix obtained from the matrix H is used, and the data obtained as a result is output to the BCH decoder 167 as the decoding result of the LDPC target data.

  In FIG. 138, as in the case of FIG. 9, the block deinterleaver 54 that performs block deinterleaving and the groupwise deinterleaver 55 that performs groupwise deinterleaving are configured separately for convenience of explanation. However, the block deinterleaver 54 and the groupwise deinterleaver 55 can be configured integrally.

  Further, in the case where the transmitting device 11 does not perform group-wise interleaving, the receiving device 12 can be configured without providing the group-wise deinterleaver 55 that performs group-wise deinterleaving.

  <LDPC decoding>

  The LDPC decoding performed by the LDPC decoder 166 of FIG. 137 will be further described.

  In the LDPC decoder 166 shown in FIG. 137, as described above, the block deinterleave and groupwise deinterleave from the groupwise deinterleaver 55 are performed, and the LDPC code of the LDPC code that is not subjected to the parity deinterleave. Decoding is performed by performing at least a column permutation equivalent to parity interleaving on the type B parity check matrix H used by the LDPC encoder 115 of FIG. 8 for LDPC encoding, and a type A parity check matrix. This is performed using a conversion check matrix (FIG. 29) obtained by performing row substitution on the matrix (FIG. 27).

  Here, by performing LDPC decoding using a transform parity check matrix, LDPC decoding that can suppress the operating frequency to a sufficiently realizable range while suppressing the circuit scale has been proposed (for example, , See Patent No. 4224777).

  First, LDPC decoding using a transform parity check matrix, which has been proposed previously, will be described with reference to FIGS. 140 to 143.

  FIG. 140 is a diagram illustrating an example of a parity check matrix H of an LDPC code having a code length N of 90 and a coding rate of 2/3.

  In FIG. 140 (also in FIGS. 141 and 142 described later), 0 is represented by a period (.).

  In parity check matrix H in FIG. 140, the parity matrix has a staircase structure.

  FIG. 141 is a diagram illustrating a parity check matrix H ′ obtained by performing row replacement of Expression (11) and column replacement of Expression (12) on the parity check matrix H of FIG.

Line replacement: 6s + t + 1 line → 5t + s + 1 line
(11)

Column replacement: 6x + y + 61st column → 5y + x + 61th column
(12)

  However, in the formulas (11) and (12), s, t, x, and y are integers in the range of 0 ≦ s <5, 0 ≦ t <6, 0 ≦ x <5, 0 ≦ t <6, respectively. It is.

  According to the row permutation of equation (11), the first, seventh, thirteenth, nineteenth and twenty-fifth rows, which are divided by six and the remainder is 1, The second, eighth, eighth, ninth, and tenth lines that are divided by the remainder of 2 are replaced with the sixth, seventh, eighth, ninth, and tenth lines, respectively.

  Further, according to the column replacement of the equation (12), the 61st column, the 61st column (parity matrix) and the 61st column, the 67th column, the 73rd column, the 79th column, and the 85th column whose remainder is 1 are divided by 61, respectively. , 62, 63, 64, and 65, the 62, 68, 74, 80, and 86 columns, which are divided by 6 and have a remainder of 2, are called 66, 67, 68, 69, and 70 columns, respectively. The replacement is performed accordingly.

  In this way, a matrix obtained by performing row and column replacement on the parity check matrix H in FIG. 140 is the parity check matrix H ′ in FIG.

  Here, even if row replacement of parity check matrix H is performed, the arrangement of code bits of the LDPC code is not affected.

  Also, the column replacement in equation (12) is the above-described information length K of parity interleaving for interleaving the K + qx + y + 1-th code bit at the position of the K + Py + x + 1-th code bit. , 60, a parallel factor P of 5, and a divisor q (= M / P) of a parity length M (in this case, 30) is 6, which corresponds to parity interleaving.

  Therefore, the parity check matrix H ′ in FIG. 141 is the K + qx + y + 1-th column of the parity check matrix H in FIG. 140 (hereinafter referred to as the original parity check matrix as appropriate) as the K + Py + x + 1-th column. This is a conversion check matrix obtained by performing at least column replacement to be replaced with this column.

If the LDPC code of the original parity check matrix H in FIG. 140 is multiplied by the same permutation as in equation (12), the transformed parity check matrix H ′ in FIG. 141 is multiplied by 0 vector. That is, if the row vector obtained by performing column substitution of Expression (12) on the row vector c as the LDPC code (one codeword) of the original check matrix H is expressed as c ′, the property of the check matrix , Hc ^T is a 0 vector, and H'c ' ^T is naturally a 0 vector.

  From the above, the conversion parity check matrix H ′ of FIG. 141 is a parity check matrix of the LDPC code c ′ obtained by performing the column replacement of Expression (12) on the LDPC code c of the original parity check matrix H.

  Therefore, the column replacement of equation (12) is performed on the LDPC code c of the original parity check matrix H, and the LDPC code c ′ after the column replacement is decoded using the transform parity check matrix H ′ of FIG. 141 (LDPC decoding). Then, the decoding result similar to the case of decoding the LDPC code of the original parity check matrix H using the parity check matrix H is obtained by performing the inverse permutation of the column permutation of the equation (12) on the decoding result. Can do.

  142 is a diagram illustrating the conversion parity check matrix H ′ of FIG. 141 with an interval in units of 5 × 5 matrices.

  In FIG. 142, the conversion parity check matrix H ′ is a 5 × 5 (= P × P) unit matrix having a parallel factor P, and a matrix in which one or more of the unit matrices are zero (hereinafter referred to as appropriate). , A quasi-unit matrix), a unit matrix or a matrix obtained by cyclic shifting a quasi-unit matrix (hereinafter referred to as a shift matrix as appropriate), a unit matrix, a quasi-unit matrix, or a sum of two or more of shift matrices It is represented by a combination of 5 × 5 0 matrices (hereinafter referred to as sum matrix as appropriate).

  142 can be said to be composed of a 5 × 5 unit matrix, a quasi-unit matrix, a shift matrix, a sum matrix, and a zero matrix. Therefore, these 5 × 5 matrices (unit matrix, quasi-unit matrix, shift matrix, sum matrix, 0 matrix) constituting the conversion check matrix H ′ are hereinafter appropriately referred to as constituent matrices.

  For decoding an LDPC code of a parity check matrix represented by a P × P configuration matrix, an architecture that performs P check node operations and P variable node operations simultaneously can be used.

  FIG. 143 is a block diagram illustrating a configuration example of a decoding device that performs such decoding.

  That is, FIG. 143 performs decoding of the LDPC code using at least the transformed parity check matrix H ′ of FIG. 142 obtained by performing column replacement of equation (12) on the original parity check matrix H of FIG. 2 shows a configuration example of a decoding device.

That is, for a constituent matrix having a weight of 2 or more, the constituent matrix is a P × P unit matrix having a weight of 1, a quasi-unit matrix in which one or more of the elements of the unit matrix are 0, or Data corresponding to the unit matrix, quasi-unit matrix, or 1 position of the shift matrix when the unit matrix or quasi-unit matrix is expressed in the form of a plurality of shift matrices obtained by cyclically shifting the unit matrix or quasi-unit matrix (identity matrix, the message corresponding to the branch belonging to quasi unit matrix or shift matrix) are stored in the same address (same FIFO from among the FIFOs 304 ₁ to 304 _18).

Hereinafter, data is also stored in the storage areas of the fourth and fifth stages in association with the conversion parity check matrix H ′. The number of stages in the storage area of the FIFO 304 ₁ is 5, which is the maximum number of 1s (Hamming weights) in the row direction in the first to fifth columns of the conversion parity check matrix H ′.

Similarly, the FIFOs 304 ₂ and 304 ₃ store data in association with the conversion parity check matrix H ′, and each has a length (number of stages) of 5. Similarly, the FIFOs 304 ₄ to 304 ₁₂ store data in association with the conversion check matrix H ′, and each has a length of 3. Similarly, the FIFOs 304 ₁₃ to 304 ₁₈ store data in association with the conversion check matrix H ′, and each has a length of 2.

  Next, the operation of the decoding apparatus in FIG. 143 will be described.

The branch data storage memory 300 is composed of six FIFOs 300 ₁ to 300 ₆ , and to which row of the conversion check matrix H ′ of FIG. 142 the five messages D311 supplied from the preceding cyclic shift circuit 308 belong. according to the information (Matrix data) D312, a FIFO to store the data, select from among the FIFO300 ₁ to 300 _6, will be stored in the order together five messages D311 to the selected FIFO. Also, the edge data storage memory 300, when reading data, sequentially reads five messages D300 ₁ from FIFO 300 _1, supplied to the next stage of the selector 301. The branch data storage memory 300 reads the messages in order from the FIFOs 300 ₂ to 300 ₆ after reading the messages from the FIFO 300 ₁ and supplies them to the selector 301.

The selector 301 selects five messages from the FIFO from which the current data is read out of the FIFOs 300 ₁ to 300 ₆ according to the select signal D301, and supplies the selected message to the check node calculation unit 302 as a message D302.

Check node calculation section 302, 302 ₁ five check node calculator to consist 302 _5, messages D302 (D302 ₁ to D302 ₅₎ supplied through the selector 301 using (messages v _i of the expression (7)), A check node operation is performed according to Equation (7), and five messages D303 (D303 ₁ to D303 ₅ ) (message u _{j in} Equation (7)) obtained as a result of the check node operation are supplied to the cyclic shift circuit 303.

The cyclic shift circuit 303 circulates the _five messages D303 ₁ to D303 ₅ obtained by the check node calculation unit 302 using unit matrices (or quasi-unit matrices) whose corresponding branches are the original in the conversion check matrix H ′. A cyclic shift is performed based on the information (Matrix data) D305 indicating whether the data has been click-shifted, and the result is supplied to the branch data storage memory 304 as a message D304.

The branch data storage memory 304 includes 18 FIFOs 304 ₁ to 304 ₁₈ , and according to information D 305 indicating which row of the conversion check matrix H ′ the five messages D 304 supplied from the preceding cyclic shift circuit 303 belong to. The FIFO for storing data is selected from the FIFOs 304 ₁ to 304 ₁₈ , and the five messages D 304 are collectively stored in the selected FIFO in order. Also, the edge data storage memory 304, when reading data, sequentially reads five messages D306 ₁ from FIFOs 304 _1, supplied to the next stage of the selector 305. Edge data storage memory 304, after completion of the data read from the FIFOs 304 _1, from FIFOs 304 ₂ to 304 _18, sequentially reads out a message, to the selector 305.

The selector 305 selects five messages from the FIFO from which the current data is read out of the FIFOs 304 ₁ to 304 ₁₈ in accordance with the select signal D307, and as the message D308, the variable node calculation unit 307 and the decoded word calculation unit 309.

  On the other hand, the received data rearrangement unit 310 rearranges the LDPC code D313 corresponding to the parity check matrix H of FIG. 140 received through the communication path 13 by performing column replacement of Expression (12), and receives the received data D314 as The data is supplied to the reception data memory 306. The reception data memory 306 calculates and stores reception LLRs (log likelihood ratios) from the reception data D314 supplied from the reception data rearrangement unit 310, and collects the reception LLRs by five as reception values D309. The variable node calculation unit 307 and the decoded word calculation unit 309 are supplied.

The variable node calculation unit 307 includes five variable node calculators 307 ₁ to 307 ₅ , a message D308 (D308 ₁ to D308 ₅ ) (message u _{j in} Expression (1)) supplied through the selector 305, and received data. using five reception values supplied from use memory 306 D309 (formula (reception values u _0i 1)), the variable node operation according to equation (1), to the message D310 (D310 ₁ not obtained as a result of the calculation D310 ₅ ) (message v _{i in} equation (1)) is supplied to the cyclic shift circuit 308.

The cyclic shift circuit 308 cyclically shifts the message D310 ₁ to D310 ₅ calculated by the variable node calculation unit 307 by a number of unit matrices (or quasi-unit matrices) whose corresponding branches are the original in the transformation check matrix H ′. A cyclic shift is performed based on the information as to whether or not the data has been obtained, and the result is supplied to the branch data storage memory 300 as a message D311.

  One round of the above operation makes it possible to perform one decoding (variable node calculation and check node calculation) of the LDPC code. The decoding apparatus in FIG. 143 decodes the LDPC code a predetermined number of times, and then obtains and outputs a final decoding result in the decoded word calculation unit 309 and the decoded data rearrangement unit 311.

That is, the decoded word calculation unit 309 includes five decoded word calculators 309 ₁ to 309 ₅ , and includes five messages D308 (D308 ₁ to D308 ₅ ) (message u _{j in} Expression (5)) output from the selector 305. Using the five reception values D309 (the reception value u _{0i in} equation (5)) supplied from the reception data memory 306, the decoding result (decoding) based on equation (5) is used as the final stage of multiple times of decoding. And the decoded data D315 obtained as a result is supplied to the decoded data rearranging unit 311.

  The decoded data rearranging unit 311 rearranges the order of the decoded data D315 supplied from the decoded word calculation unit 309 by performing the column replacement in the formula (12), and obtains the final decoding result. Output as D316.

  As described above, one or both of row permutation and column permutation is applied to the parity check matrix (original parity check matrix), and one or more of the P × P unit matrix and one of its elements is set to 0. A quasi-unit matrix, a unit matrix or a shift matrix obtained by cyclically shifting a quasi-unit matrix, a unit matrix, a quasi-unit matrix, a sum matrix that is a sum of shift matrices, or a combination of P × P 0 matrices, By converting to a parity check matrix (conversion parity check matrix) that can be represented by a combination of constituent matrices, decoding of LDPC code, check node operation and variable node operation, P smaller than the number of rows and columns of the parity check matrix It is possible to adopt an architecture that performs them simultaneously. When adopting an architecture that performs P operations of node operations (check node operation and variable node operation) at the same time, which is smaller than the number of rows and columns of the check matrix, the number of node operations equal to the number of rows and columns of the check matrix As compared with the case where only the simultaneous operation is performed, a large number of iterative decoding can be performed while the operating frequency is limited to a realizable range.

  The LDPC decoder 166 constituting the receiving device 12 in FIG. 137 performs LDPC decoding by simultaneously performing P check node operations and P variable node operations, for example, similarly to the decoding device in FIG. 143.

  That is, for the sake of simplicity, the parity check matrix of the LDPC code output from the LDPC encoder 115 that constitutes the transmission apparatus 11 of FIG. 8 is, for example, the parity matrix shown in FIG. , The parity interleaver 23 of the transmission apparatus 11 interleaves the K + qx + y + 1-th code bit at the position of the K + Py + x + 1-th code bit. However, the information length K is set to 60, the parallel factor P is set to 5, and the divisor q (= M / P) of the parity length M is set to 6.

  As described above, since this parity interleaving corresponds to the column replacement of equation (12), the LDPC decoder 166 does not need to perform column replacement of equation (12).

  For this reason, in the receiving device 12 of FIG. 137, as described above, the group-wise deinterleaver 55 sends the LDPC decoder 166 the LDPC code that has not been subjected to parity deinterleaving, that is, the sequence of equation (12). The LDPC code in a state where the replacement is performed is supplied, and the LDPC decoder 166 performs the same processing as that of the decoding device in FIG. 143 except that the column replacement of Expression (12) is not performed.

  That is, FIG. 144 is a diagram illustrating a configuration example of the LDPC decoder 166 of FIG.

  In FIG. 144, the LDPC decoder 166 is configured in the same manner as the decoding device of FIG. 143 except that the received data rearrangement unit 310 of FIG. 143 is not provided, and the column replacement of Expression (12) is performed. Except for the above, since the same processing as that of the decoding device of FIG. 143 is performed, the description thereof is omitted.

  As described above, since the LDPC decoder 166 can be configured without the reception data rearrangement unit 310, the scale can be reduced as compared with the decoding apparatus in FIG.

  140 to 144, for simplicity of explanation, the code length N of the LDPC code is 90, the information length K is 60, and the parallel factor (the number of rows and columns of the constituent matrix) P is 5. , The divisor q (= M / P) of the parity length M is 6 and the code length N, the information length K, the parallel factor P, and the divisor q (= M / P) are described above. It is not limited to the value.

  That is, in the transmission apparatus 11 of FIG. 8, the LDPC encoder 115 outputs, for example, a code length N of 64800, 16200, 69120, etc., an information length K of N-Pq (= NM), and a parallel factor P 360 and divisor q are M / P, respectively. The LDPC decoder 166 of FIG. 144 simultaneously performs P check node operations and variable node operations on such LDPC codes. Thus, the present invention can be applied when LDPC decoding is performed.

  When the LDPC code is decoded by the LDPC decoder 166, the parity part of the decoded result is unnecessary, and when only the information bits of the decoded result are output, the LDPC decoder 166 without the decoded data rearranging unit 311 is output. Can be configured.

  <Configuration Example of Block Deinterleaver 54>

  FIG. 145 is a diagram for explaining block deinterleaving performed by the block deinterleaver 54 in FIG. 138.

  In block deinterleaving, processing reverse to block interleaving of the block interleaver 25 described in FIG. 123 is performed, so that the arrangement of code bits of the LDPC code is restored (restored).

  That is, in block deinterleaving, for example, as in block interleaving, the LDPC code is written to and read from m columns equal to the number m of symbol bits, whereby the arrangement of code bits of the LDPC code is restored to the original sequence. Returned.

  However, in block deinterleaving, LDPC codes are written in the order in which LDPC codes are read out in block interleaving. Further, in block deinterleaving, LDPC codes are read in the order in which LDPC codes are written in block interleaving.

  That is, as for part 1 of the LDPC code, as shown in FIG. 145, part 1 of the LDPC code in m-bit symbol units is written in the row direction from the first row of all m columns. That is, the sign bit of the LDPC code that is an m-bit symbol is written in the row direction.

  The writing of part 1 in m-bit units is sequentially performed toward the lower row of m columns, and when the writing of part 1 is completed, as shown in FIG. Reading part 1 from down to down is done from left to right column.

  When reading to the rightmost column is completed, as shown in FIG. 145, it returns to the leftmost column, and reading part 1 from the top to the bottom of the second column unit of the column Thereafter, part 1 of the LDPC code of one codeword is read in the same manner.

  When the reading of part 1 of the LDPC code of one codeword is completed, for part 2 in m-bit symbol units, the m-bit symbol units are sequentially concatenated after part 1, and as a result, symbol units This LDPC code is returned as a sequence of code bits of the LDPC code (LDCP code before block interleaving) of the original one codeword.

  <Another configuration example of the bit deinterleaver 165>

  FIG. 146 is a block diagram illustrating another configuration example of the bit deinterleaver 165 of FIG.

  In the figure, portions corresponding to those in FIG. 138 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  In other words, the bit deinterleaver 165 in FIG. 146 has the same configuration as that in FIG. 138 except that a parity deinterleaver 1011 is newly provided.

  In FIG. 146, the bit deinterleaver 165 includes a block deinterleaver 54, a groupwise deinterleaver 55, and a parity deinterleaver 1011. The bit deinterleaver 165 performs bit deinterleaving of code bits of the LDPC code from the demapper 164. .

  In other words, the block deinterleaver 54 targets the LDPC code from the demapper 164, and performs block deinterleave corresponding to the block interleave performed by the block interleaver 25 of the transmission apparatus 11 (block inverse interleaving process), that is, block interleave. Block deinterleaving is performed to return the position of the code bit replaced by the original position to the original position, and the resulting LDPC code is supplied to the groupwise deinterleaver 55.

  The groupwise deinterleaver 55 performs groupwise deinterleaving corresponding to the groupwise interleaving as the rearrangement process performed by the groupwise interleaver 24 of the transmission device 11 on the LDPC code from the block deinterleaver 54.

  The LDPC code obtained as a result of groupwise deinterleaving is supplied from the groupwise deinterleaver 55 to the parity deinterleaver 1011.

  The parity deinterleaver 1011 targets the code bit after groupwise deinterleaving in the groupwise deinterleaver 55, and performs parity deinterleaving corresponding to the parity interleaving performed by the parity interleaver 23 of the transmission device 11 (inverse of parity interleaving). In other words, parity deinterleaving is performed to return the code bits of the LDPC code whose arrangement has been changed by parity interleaving to the original order.

  The LDPC code obtained as a result of parity deinterleaving is supplied from the parity deinterleaver 1011 to the LDPC decoder 166.

  Therefore, in the bit deinterleaver 165 of FIG. 146, the LDPC decoder 166 has the LDPC code subjected to block deinterleaving, groupwise deinterleaving, and parity deinterleaving, that is, LDPC coding according to the check matrix H. The LDPC code obtained by is supplied.

  The LDPC decoder 166 performs LDPC decoding of the LDPC code from the bit deinterleaver 165 using the parity check matrix H used by the LDPC encoder 115 of the transmission device 11 for LDPC encoding.

  That is, for the type B scheme, the LDPC decoder 166 uses the LDPC decoding of the LDPC code from the bit deinterleaver 165 and the LDPC encoder 115 of the transmission apparatus 11 for the LDPC encoding (type B scheme) check matrix H This is used as it is or by using a conversion parity check matrix obtained by performing at least column replacement corresponding to parity interleaving on the parity check matrix H. Also, for the type A scheme, the LDPC decoder 166 uses the LDPC decoding of the LDPC code from the bit deinterleaver 165 and the parity check matrix (for the type A scheme) used by the LDPC encoder 115 of the transmission apparatus 11 for the LDPC encoding ( 27) using a parity check matrix obtained by performing column substitution (FIG. 28) or a transform parity check matrix obtained by performing row substitution on the parity check matrix used in LDPC encoding (FIG. 27) (FIG. 29). Do.

  Here, in FIG. 146, since the LDPC code obtained by LDPC encoding according to the check matrix H is supplied from the bit deinterleaver 165 (its parity deinterleaver 1011) to the LDPC decoder 166, the LDPC The LDPC decoding of the code is column-replaced with the type B parity check matrix H itself used by the LDPC encoder 115 of the transmitter 11 for LDPC encoding or the type A parity check matrix (FIG. 27) used for LDPC encoding. When performing using the parity check matrix (FIG. 28) obtained by performing the above, the LDPC decoder 166, for example, performs full message processing (check node message, variable node message) sequentially by one node at a time. Decoding device that performs LDPC decoding by coding (full serial decoding) method and message calculation for all nodes simultaneously (in parallel) It can be composed of a decoding device for performing LDPC decoding by full parallel decoding (full parallel decoding) scheme.

  Also, the LDPC decoder 166 performs LDPC decoding of the LDPC code by performing at least column replacement corresponding to parity interleaving on the type B check matrix H used by the LDPC encoder 115 of the transmission apparatus 11 for LDPC encoding. When the conversion check matrix obtained or the conversion check matrix (FIG. 29) obtained by performing row substitution on the type A check matrix (FIG. 27) used for LDPC encoding is used, the LDPC decoder 166 is used. Is a decoding device of an architecture that simultaneously performs P (or a divisor other than 1 of P) number of check node operations and variable node operations, and is similar to column permutation (parity interleaving) for obtaining a conversion check matrix This is configured by a decoding device (FIG. 143) having a received data rearrangement unit 310 that rearranges the code bits of the LDPC code by performing column replacement on the LDPC code. It is possible.

  In FIG. 146, for convenience of explanation, a block deinterleaver 54 that performs block deinterleaving, a groupwise deinterleaver 55 that performs groupwise deinterleaving, and a parity deinterleaver 1011 that performs parity deinterleaving are illustrated. However, two or more of the block deinterleaver 54, the groupwise deinterleaver 55, and the parity deinterleaver 1011 are included in the parity interleaver 23, the groupwise interleaver 24, And like the block interleaver 25, it can comprise integrally.

  FIG. 149 is a block diagram illustrating a third configuration example of the reception system to which the reception device 12 can be applied.

  In the figure, portions corresponding to those in FIG. 147 are denoted by the same reference numerals, and description thereof will be omitted below as appropriate.

  The reception system of FIG. 149 is common to the case of FIG. 147 in that it includes an acquisition unit 1101 and a transmission path decoding processing unit 1102.

  <One Embodiment of Computer>

  Next, the series of processes described above can be performed by hardware or software. When a series of processing is performed by software, a program constituting the software is installed in a general-purpose computer or the like.

  Therefore, FIG. 150 shows a configuration example of an embodiment of a computer in which a program for executing the above-described series of processing is installed.

  The program can be recorded in advance in a hard disk 705 or a ROM 703 as a recording medium built in the computer.

  Alternatively, the program is stored temporarily on a removable recording medium 711 such as a flexible disk, a CD-ROM (Compact Disc Read Only Memory), an MO (Magneto Optical) disc, a DVD (Digital Versatile Disc), a magnetic disc, or a semiconductor memory. It can be stored permanently (recorded). Such a removable recording medium 711 can be provided as so-called package software.

  The program is installed on the computer from the removable recording medium 711 as described above, or transferred from the download site to the computer via a digital satellite broadcasting artificial satellite, or a LAN (Local Area Network), The program can be transferred to a computer via a network such as the Internet. The computer can receive the program transferred in this way by the communication unit 708 and install it in the built-in hard disk 705.

When a command is input by being equalized, a program stored in a ROM (Read Only Memory) 703 is executed accordingly. Alternatively, the CPU 702 may be a program stored in the hard disk 705, a program transferred from a satellite or a network, received by the communication unit 708 and installed in the hard disk 705, or a removable recording medium 711 installed in the drive 709.

Thereby, the CPU 702 performs processing according to the above-described flowchart or processing performed by the configuration of the above-described block diagram. Then, the CPU 702 outputs the processing result from the output unit 706 configured with an LCD (Liquid Crystal Display), a speaker, or the like, for example, via the input / output interface 710 or the communication unit 708 as necessary. Transmission and further recording on the hard disk 705 are performed.

  Here, in this specification, the processing steps for describing a program for causing a computer to perform various types of processing do not necessarily have to be processed in time series according to the order described in the flowchart, but in parallel or individually. This includes processing to be executed (for example, parallel processing or processing by an object).
