Description

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

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

Recent studies have shown that LDPC codes can achieve performance close to the Shannon limit as the code length increases, similar to turbo codes and the like. In addition, LDPC codes have the property that the minimum distance is proportional to the code length, so as their characteristics, block error probability characteristics are good, and furthermore, the so-called error floor phenomenon observed in decoding characteristics such as turbo codes is reduced. Another advantage is that it rarely occurs.

ATSC Standard: Physical Layer Protocol (A/322), 7 September 2016

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

Data transmission using LDPC codes as described above is spreading worldwide, and there is a demand to ensure good communication (transmission) quality.

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

A first transmission method/apparatus of the present technology includes an encoding step/unit that performs LDPC encoding based on an LDPC code parity check matrix having a code length N of 69120 bits and an encoding rate r of 7/16; A group-wise interleaving step/unit that performs group-wise interleaving that interleaves the LDPC code in units of 360-bit bit groups, and the LDPC code in units of 2 bits, four signal points of QPSK (Quadrature Phase Shift Keying) In the group-wise interleaving, the i + 1-th bit group from the beginning of the LDPC code is set as a bit group i, and the bits of the 69120-bit LDPC code The sequence of groups 0 through 191 is the

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 have to be binary, but here it will be described as being binary.

The LDPC code is most 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 matrix elements is very small (a matrix in which most of the elements are 0).

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

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

In coding by LDPC code (LDPC coding), for example, a generator matrix G is generated based on parity check matrix H, and by multiplying binary information bits by this generator matrix G, a codeword (LDPC code ) is generated.

Specifically, an encoding apparatus that performs LDPC encoding first calculates a generator matrix G that satisfies the formula G ^T =0 between the parity check matrix H and the transposed matrix H ^T . Here, when the generator matrix G is a K×N matrix, the encoding device multiplies the generator matrix G by a bit string of information bits (vector u) consisting of K bits to obtain a code consisting of N bits. Generate the word c(=uG). A codeword (LDPC code) generated by this encoding device is received by the receiving side via a predetermined communication channel.

The decoding of the LDPC code is an algorithm proposed by Gallager called Probabilistic Decoding, which consists of a variable node (also called a message node) and a check node. can be done by a message passing algorithm by 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 flow chart showing the procedure for decoding an LDPC code.

Hereinafter, a real value (receiving LLR ) is also called the received value u _0i . Let u _j be the message output from the check node, and v _i be the message output from the variable node.

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 as a counter for the iterative process is initialized to "0", and the process proceeds to step S12. In step S12, the message (variable node message) v _i is obtained by performing the calculation (variable node calculation) shown in Equation (1) based on the received value u _0i obtained by receiving the LDPC code, and further, Based on this message v _i , message u _j is obtained by performing the operation (check node operation) shown in Equation (2).

Here, d _v and d _c in equations (1) and (2) can be arbitrarily selected to indicate the number of “1”s in the vertical direction (column) and the horizontal direction (row) of parity check matrix H, respectively. parameter. For example, in the case of an LDPC code (( _3,6 ) LDPC code) for parity check matrix H with a column weight of 3 and a row weight of 6 as _shown in FIG. Become.

In addition, in the variable node calculation of formula (1) and the check node calculation of (2), the message input from the edge (the line connecting the variable node and the check node) to output the message is is not subject to calculation, the range of calculation is 1 to d _v -1 or 1 to d _c -1. In addition, the check node operation of formula (2) actually creates in advance a table of function R(v ₁ , v ₂ ) shown in formula (3) defined by one output for two inputs v ₁ and v ₂ . This is done by continuously (recursively) using this as shown in equation (4).

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

If it is determined in step S13 that the variable k is greater than C, the process proceeds to step S14, where the message v _i as the decoding result to be finally output is obtained by performing the calculation shown in equation (5). is output, and the decoding process of the LDPC code ends.

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

FIG. 3 is a diagram showing an example of parity check matrix H of (3,6) LDPC code (coding rate ½, code length 12).

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

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

Here, in FIG. 4, a check node is represented by a plus "+", and a variable node is represented by an equals "=". A check node and a variable node correspond to rows and columns of the parity check matrix H, respectively. A connection between the check node and the variable node is an edge, which corresponds to the element "1" of the parity check matrix.

That is, when the element of the j-th row and i-th column of the parity check matrix is 1, in FIG. +" nodes) are connected by branches. A branch indicates that a code bit corresponding to a variable node has a constraint condition corresponding to a check node.

In the Sum Product Algorithm, which is a decoding method for LDPC codes, variable node operations and check node operations are repeatedly performed.

FIG. 5 is a diagram showing variable node operations performed at variable nodes.

At the variable node, the message v _i corresponding to the branch to be calculated is the message _{u 1} and u ₂ from the remaining branches connected to the variable node and the variable node Calculated by calculation. Messages corresponding to other branches are similarly sought.

FIG. 6 is a diagram showing check node operations performed at check nodes.

Here, the check node operation of formula (2) uses the relation of formula 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.

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

・・・（７）

... (7)

At the check node, the check node operation of equation (2) is performed according to equation (7).

That is, at 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 operation of equation (7) using ₅ . Messages corresponding to other branches are similarly sought.

Note that the function φ(x) in Equation (7) can be expressed by the formula 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 implemented in hardware, they may be implemented 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 an example of a transmission system to which the present technology is applied (a system refers to an entity in which a plurality of devices are logically aggregated, and it does not matter whether or not devices of each configuration are in the same housing). It is a figure which shows the structural example of embodiment.

In FIG. 7, the transmission system is composed of a transmitter 11 and a receiver 12 .

The transmission device 11 transmits (broadcasts) (transmits), for example, television broadcast programs. That is, the transmitting 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), etc. It transmits via the communication channel 13 .

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

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

On the other hand, the communication path 13 may generate burst errors or erasures. For example, especially 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) ), depending on the delay of the echo (paths other than the main path), the power of a particular symbol may be erasured.

In addition, even in flutter (a communication channel where echo with a delay of 0 and a Doppler frequency is added), if D/U is 0 dB, the Doppler frequency will change OFDM at a specific time. There are cases where the power of the entire symbol is erasure.

Furthermore, due to the wiring situation from the reception unit (not shown) such as an antenna that receives the signal from the transmission device 11 to the reception device 12 on the reception device 12 side, and the unstable power supply of the reception device 12, burst errors may occur.

On the other hand, in the decoding of the _LDPC code, as shown in FIG. Since the variable node operation of equation (1) is performed with addition, if an error occurs in the sign bit used in the variable node operation, the accuracy of the desired message is reduced.

Then, in the decoding of the LDPC code, at the check node, the check node operation of Equation (7) is performed using the message obtained at the variable node connected to the check node, so that the multiple connected variable nodes ( If the number of check nodes in which the code bits of the LDPC code corresponding to ) are simultaneously in error (including erasures), the decoding performance deteriorates.

That is, for example, if two or more of the variable nodes connected to the check node become erasure at the same time, the check node sends a message with the same probability that the value is 0 and that the value is 1. return. In this case, the check nodes that return messages with equal probability do not contribute to one decoding process (one set of variable node operations and check node operations), and as a result, the number of iterations of the decoding process is increased. As a result, the decoding performance deteriorates, and the power consumption of the receiving device 12 that decodes the LDPC code increases.

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

<Configuration example of transmission device 11>

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

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

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 padder 112. .

Pader 112 performs the necessary zero padding (null insertion) on the data from mode adaptation/multiplexer 111 and supplies the resulting data to BB Scrambler 113 .

A BB scrambler 113 applies BB scrambling (Base-Band Scrambling) to the data from the padder 112 and supplies the resulting data to a BCH encoder (BCH encoder) 114 .

The BCH encoder 114 BCH-encodes the data from the BB scrambler 113 and supplies the resulting data to an LDPC encoder 115 as LDPC target data to be LDPC-encoded.

The LDPC encoder 115 performs LDPC encoding on the LDPC target data from the BCH encoder 114, for example, according to a check matrix in which the parity matrix, which is a part corresponding to the parity bits of the LDPC code, has a dual diagonal structure. and outputs an LDPC code with the LDPC target data as information bits.

That is, the LDPC encoder 115 converts the LDPC target data to a predetermined standard such as DVB-S.2, DVB-T.2, DVB-C.2, ATSC 3.0 (the parity check matrix (Corresponding) LDPC code, LDPC encoding for encoding into other LDPC codes is performed, and the resulting LDPC code is output.

Here, the LDPC code specified in the DVB-S.2 and ATSC3.0 standards is an IRA (Irregular Repeat Accumulate) code, and (a part or all of) the parity matrix in the parity check matrix of the LDPC code is A staircase structure. A parity matrix and a staircase structure will be described later. For IRA codes, see, for example, "Irregular Repeat-Accumulate Codes," H. Jin, A. Khandekar, and R. J. McEliece, in Proceedings of 2nd International Symposium on Turbo codes and Related Topics, pp. 1-8, Sept. 2000.

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

The bit interleaver 116 performs bit interleaving, which will be described later, on the LDPC code from the LDPC encoder 115 , and supplies the LDPC code after the bit interleaving to the 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 units) of the LDPC code, thereby performing orthogonal modulation (multiple modulation). value modulation).

That is, the mapper 117 converts the LDPC code from the bit interleaver 116 onto a constellation that is an IQ plane defined by the I-axis representing the I component in phase with the carrier and the Q-axis representing the Q component orthogonal to the carrier. are mapped to the signal points determined by the modulation scheme for orthogonal modulation of the LDPC code, and orthogonal modulation is performed.

When the number of signal points of the constellation used in the modulation method of orthogonal modulation performed by the mapper 117 is 2 ^m , the mapper 117 uses m code bits of the LDPC code as a symbol (1 symbol), The LDPC code from bit interleaver 116 is mapped on a symbol-by-symbol basis to a signal point representing a symbol among the 2 ^m signal points.

Here, as the modulation method of the quadrature modulation performed by the mapper 117, for example, the modulation method stipulated in the DVB-S.2 or ATSC3.0 standards, or other modulation method, that is, 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. Which modulation scheme is to be used for quadrature modulation in the mapper 117 is set in advance according to, for example, the operation of the operator of the transmission device 11 or the like.

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

The time interleaver 118 performs time interleaving (time direction interleaving) on the data from the mapper 117 in units of symbols, and converts the resulting data into a SISO/MISO encoder (SISO/MISO (Single Input Single Output/Multiple Input)). input (single output) encoder) 119.

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

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

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

The BCH encoder 121 BCH-encodes 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 LDPC-encodes 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 .

The mapper 123, like the mapper 117, maps the LDPC code from the LDPC encoder 122 to a signal point representing one symbol of orthogonal modulation in units of one or more code bits (symbol units) of the LDPC code. quadrature modulation, and the resulting data is supplied to frequency interleaver 124 .

Similar to frequency interleaver 120 , frequency interleaver 124 frequency-interleaves the data from mapper 123 on a symbol-by-symbol basis and supplies the data to frame builder/resource allocation section 131 .

Frame builder/resource allocation unit 131 inserts pilot symbols into required positions of data (symbols) from frequency interleavers 120 and 124, and from the resulting data (symbols), a predetermined 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 .

OFDM generating section 132 generates an OFDM signal corresponding to the frame from frame from frame builder/resource allocation section 131 and transmits it via communication channel 13 (FIG. 7).

Note that the transmission device 11 may be configured without 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. can be done.

<Configuration example of bit interleaver 116>

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

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

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

Group-wise interleaver 24 performs group-wise interleaving on the LDPC code from parity interleaver 23 and supplies the LDPC code after group-wise interleaving to block interleaver 25 .

Here, in group-wise interleaving, the LDPC code for one code is divided into 360-bit units equal to the parallel factor P described later from the beginning, and the 360 bits of one division are used as a bit group, and the parity interleaver 23 LDPC codes from are interleaved in bit groups.

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, for example, converting one code worth of LDPC code into a symbol of m bits, which is a unit of mapping. and supplied to 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 arranged in the row (horizontal) direction by a number equal to the number of bits m of a symbol. The LDPC code from the group-wise interleaver 24 is written in the column direction and read out in the row direction to the storage areas arranged in the same manner as the LDPC code, so that the LDPC code is symbolized into m-bit symbols.

<Parity Check Matrix of LDPC Code>

FIG. 10 is a diagram showing an example of 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 includes an information matrix H _A of a portion corresponding to the information bit of the code bits of the LDPC code, and a parity matrix H _T corresponding to the parity bit. can be represented by the formula H=[H _A |H _T ] (a matrix in which the elements of the information matrix H _A are the elements on the left side and the elements of the parity matrix H _T are the elements on the right side).

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

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

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

As the parity matrix H _T of the parity check matrix H used for LDPC encoding in the LDPC encoder 115, for example, a parity matrix H _T similar to the parity matrix H of the LDPC code specified in standards such as DVB-T.2. can be adopted.

The parity matrix H _T of the parity check matrix H of the LDPC code specified in standards such as DVB-T.2 is, as shown in FIG. matrix). The row weight of the parity matrix H _T is 1 for the first row and 2 for all remaining rows. Also, the column weight is 1 for the last column and 2 for all remaining columns.

As described above, an LDPC code for a parity check matrix H whose parity matrix H _T has a staircase structure can be easily generated using the parity check matrix H.

That is, an LDPC code (one codeword) is represented by a row vector c, and a column vector obtained by transposing the row vector is represented by ^cT . Also, in the row vector c of the LDPC code, the information bit portion is represented by row vector A, and the parity bit portion is represented by row vector T. FIG.

In this case, the row vector c is obtained by the formula c = [A|T] (where the elements of row vector A are the elements on the left, row vector T can be represented as a row vector with the element of the right as the element of

The check matrix H and the row vector c = [A|T] as the LDPC code must satisfy the expression Hc ^T = 0, and the row vector c = [A | T] that satisfies the expression Hc ^T = 0 If the parity matrix H _T of parity check matrix ^H = [H _A |H _T ] has the staircase structure shown in FIG. By setting the elements of each row to 0 in order from the first row of the column vector Hc ^T , it is possible to obtain them sequentially (in order).

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

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

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

FIG. 13 is a diagram showing the number of columns KX, K3 and M and the column weight X for each coding rate r of the LDPC code specified in standards such as DVB-T.2.

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

And for LDPC code with code length N of 64800 bits, 11 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 specified, and for an LDPC code with a code length N of 16200 bits, ten coding rates 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6 and 8/9 are provided.

Here, hereinafter, the code length N of 64800 bits is also referred to as 64 kbits, and the code length N of 16200 bits is also referred to as 16 kbits.

As for the LDPC code, code bits corresponding to columns with higher column weights in the check matrix H tend to have lower error rates.

12 and 13, in the parity check matrix H specified in standards such as DVB-T.2, the column weight tends to be larger toward the top (left side) of the column. As for the LDPC code corresponding to H, the leading code bit tends to be more resistant to errors (tolerant to errors), and the trailing code bit tends to be less resistant to errors.

<Parity interleave>

Parity interleaving by parity interleaver 23 in FIG. 9 will be described with reference to FIGS.

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

As shown in FIG. 14, when a plurality of (such as two) variable nodes (corresponding code bits) connected to the check node become errors such as erasure at the same time, all the check nodes connected to the check node Returns to the variable node a message with an equal probability of a value of 0 and a value of 1. Therefore, if a plurality of variable nodes connected to the same check node become erasures at the same time, the decoding performance deteriorates.

By the way, the LDPC code output by the LDPC encoder 115 in FIG. 8 is, for example, an IRA code similar to the LDPC code specified in standards such as DVB-T.2, and the parity matrix HT of the parity check matrix _H is , as shown in FIG. 11, has a staircase structure.

FIG. 15 is a diagram showing an example of a parity matrix H _T having a staircase structure and a Tanner graph corresponding to the parity matrix H _T as shown in FIG. 11 .

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 FIG. 15A.

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

Therefore, if parity bits corresponding to two adjacent variable nodes described above become erroneous at the same time due to a burst error, erasure, or the like, two variable nodes corresponding to the two erroneous parity bits (using parity bits A check node connected to a variable node that requests a message) returns a message with an equal probability of 0 and 1 to the variable node connected to the check node, so the decoding performance is reduced. to degrade. When the burst length (the number of parity bits with consecutive errors) increases, the number of check nodes returning messages with equal probability increases, further deteriorating the decoding performance.

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

FIG. 16 is a diagram showing parity matrix H _T of parity check matrix H corresponding to the LDPC code after parity interleaving performed by parity interleaver 23 of FIG.

Here, the information matrix H _A of the parity check matrix H corresponding to the LDPC code output by the LDPC encoder 115 is similar to the information matrix of the parity check matrix H corresponding to the LDPC code specified in standards such as DVB-T.2 In addition, it has a circular structure.

A cyclic structure is a structure in which a column matches a cyclically shifted version of another column. columns are 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. Hereinafter, the P columns in the cyclic structure are referred to as parallel factors as appropriate.

As LDPC codes specified in standards such as DVB-T.2, there are two types of LDPC codes with code lengths N of 64800 bits and 16200 bits, as described with reference to FIGS. For both types of LDPC codes, the parallel factor P is defined as 360, which is one of the divisors of the parity length M, excluding 1 and M.

Also, the parity length M is a value other than a prime number represented by the formula M=q×P=q×360 using a value q that varies depending on the coding rate. Therefore, the value q, like the parallel factor P, is also one of the divisors of the parity length M, excluding 1 and M, and dividing the parity length M by the parallel factor P (The product of P and q, which is a divisor of the parity length M, gives the parity length M).

As described above, the parity interleaver 23 has an information length of K, an integer of 0 or more and less than P is x, and an integer of 0 or more and less than q is y. As a parity interleave, N-bit LDPC Among the code bits of the code, interleave the K+qx+y+1th code bit into the position of the K+Py+x+1th code bit.

Both the K+qx+y+1th code bit and the K+Py+x+1th code bit are the code bits after the K+1th code bit, so they are parity bits. Interleaving moves the position of the parity bit of the LDPC code.

According to such parity interleaving, (parity bits corresponding to) variable nodes connected to the same check node are separated by a parallel factor P, ie, 360 bits here, so 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 become erroneous at the same time, and as a result, it is possible to improve robustness against burst errors.

Note that the LDPC code after parity interleaving, which interleaves the K+qx+y+1st code bit at the position of the K+Py+x+1th code bit, is K+qx+ Matches the LDPC code of a parity check matrix obtained by performing column permutation in which the y+1-th column is replaced with the K+Py+x+1-th column (hereinafter also referred to as a transformed parity check matrix).

In addition, as shown in FIG. 16, the parity matrix of the transform check matrix has a pseudo-cyclic structure in units of P columns (360 columns in FIG. 16).

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

The transform parity check matrix obtained by applying column permutation corresponding to parity interleaving to the parity check matrix of the LDPC code specified in standards such as DVB-T.2 is 360 rows in the upper right corner of the transform parity check matrix. In the 360 column part (shift matrix described later), there is only one element of 1 (it is an element of 0), and in that respect, it is not a (complete) cyclic structure, but a pseudo-cyclic structure. ing.

The transformed parity check matrix for the parity check matrix of the LDPC code output by the LDPC encoder 115 has, for example, a pseudo-cyclic structure similar to the transformed parity check matrix for the parity check matrix of the LDPC code specified in standards such as DVB-T.2. ing.

Note that the transformation parity check matrix of FIG. 16 is a column permutation corresponding to parity interleaving with respect to the original parity check matrix H, and also a row permutation so that the transformation parity check matrix is composed of constituent matrices described later. (row permutation) is also applied to the matrix.

FIG. 17 is a flowchart illustrating the processing performed by the LDPC encoder 115, bit interleaver 116, and 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 symbols 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 on the LDPC code from the LDPC encoder 115, and converts the parity-interleaved LDPC code into group-wise interleaved It feeds the leaver 24 .

Group-wise interleaver 24 performs group-wise interleaving on the LDPC code from parity interleaver 23 and supplies it to 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 m-bit symbols obtained as a result to the mapper 117 .

In step S103, the mapper 117 maps the symbols from the block interleaver 25 to any one of 2 ^m signal points determined by the modulation scheme of the orthogonal modulation performed by the mapper 117 and orthogonally modulates them. The data is provided to time interleaver 118 .

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

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

That is, both parity interleaving and groupwise interleaving can be performed by writing and reading code bits to and from memory, and the address for writing code bits (write address) is the address for reading code bits. It can be represented by a matrix that translates to (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 code bits using these matrices. A result of group-wise interleaving the LDPC code after parity interleaving can be obtained.

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

That is, the 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 group-wise interleaving, and a matrix representing block interleaving is obtained, parity interleaving, group-wise interleaving, and block interleaving can be performed using these matrices. Interleaving can be done in bulk.

Note that one or the amount of parity interleaving and group-wise interleaving may be omitted.

<Configuration example of LDPC encoder 115>

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

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

As described with reference to FIGS. 12 and 13, standards such as DVB-T.2 define two types of LDPC codes with a code length N of 64800 bits and 16200 bits.

And for the LDPC code whose code length N is 64800 bits, 11 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 specified, and for an LDPC code with a code length N of 16200 bits, ten 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).

The LDPC encoder 115, for example, encodes (error correction encoding) by the LDPC code of each encoding rate such that the code length N is 64800 bits or 16200 bits, for each code length N and each encoding rate It can be performed according to the prepared check matrix H.

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

The LDPC encoder 115 is composed of 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 encoding parity calculation unit 615, and a control unit 616. The LDPC encoder LDPC encoding is performed on the LDPC target data supplied to 115, and the resulting LDPC code is supplied to bit interleaver 116 (FIG. 8).

That is, the coding rate setting unit 611 sets, for example, the code length N and the coding rate r of the LDPC code, and other specific information for identifying the LDPC code, according to the operator's operation or the like.

Initial value table reading section 612 reads from storage section 602 a later-described parity check matrix initial value table representing the parity check matrix of the LDPC code specified by the specific information set by coding rate setting section 611 .

The parity check matrix generating 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, parity check matrix generating section 613 generates information matrix H _A corresponding to information length K (= code length N-parity length M) according to code length N and coding rate r set by coding rate setting section 611. A parity check matrix H is generated by arranging 1 elements in the column direction at intervals of 360 columns (parallel factor P) and stored in the storage unit 602 .

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

Encoding parity calculation section 615 reads parity check matrix H generated by parity check matrix generation section 613 from storage section 602, and uses parity bit for the information bit read by information bit reading section 614 to obtain a predetermined parity bit. A codeword (LDPC code) is generated by calculating based on the equation.

A control unit 616 controls each block constituting the encoding processing unit 601 .

Storage unit 602 stores, for example, a plurality of parity check matrix initial value tables corresponding to the plurality of coding rates shown in FIGS. 12 and 13 for each code length N such as 64800 bits and 16200 bits. It is The storage unit 602 also temporarily stores data necessary for the processing of the encoding processing unit 601 .

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

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

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

In step S203, the parity check matrix generating unit 613 uses the parity check matrix initial value table read from the storage unit 602 by the initial value table reading unit 612, 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 extracts the information length K (=N ×r) information bits are read, and parity check matrix H obtained by parity check matrix generation section 613 is read out from storage section 602 and supplied to encoding parity calculation section 615 .

In step S205, the encoding parity calculation unit 615 uses the information bits from the information bit reading unit 614 and the parity check matrix H to sequentially calculate the parity bits of the codeword c that satisfy equation (8).

^HcT = 0
... (8)

In Equation (8), c represents a row vector as a codeword (LDPC code), and c ^T represents transposition of row vector c.

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

The check matrix H and the row vector c = [A|T] as the LDPC code must satisfy the expression Hc ^T = 0, and the row vector c = [A | T] that satisfies the expression Hc ^T = 0 If the parity matrix H _T of parity check matrix ^H = [H _A |H _T ] has the staircase structure shown in FIG. By setting the elements of each row to 0 in order from the first row of the column vector Hc ^T , it is possible to obtain them sequentially.

Encoding parity computing section 615 obtains parity bit T for information bit A from information bit reading section 614, and codeword c represented by information bit A and parity bit T = [A|T] is output as the LDPC encoding result of information bit A.

Thereafter, in step S206, control section 616 determines whether or not to end LDPC encoding. In step S206, if it is determined not to end the LDPC encoding, i.e., for example, if there is still LDPC target data to be LDPC encoded, the process returns to step S201 (or step S204). The processing of S201 (or steps S204) to S206 is repeated.

If it is determined in step S206 that the LDPC encoding should be terminated, that is, if there is no LDPC target data to be LDPC-encoded, the LDPC encoder 115 terminates the process.

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

<Example of check matrix initial value table>

The parity check matrix initial value table is, for example, an information matrix H _A ( 10) for each 360 columns (parallel factor P), and is created in advance for each parity 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 the element of 1 in the information matrix H _A for every 360 columns (parallel factor P).

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

Hereinafter, the expression method of the parity check matrix initial value table representing the parity check matrix in which part of the parity matrix H _T has a staircase structure and the remaining portion is a diagonal matrix is also referred to as a type A method. Also, the expression method of the parity check matrix initial value table representing the parity check matrix in which the entire parity matrix H _T has a staircase structure is also called the type B method.

An LDPC code for a parity check matrix represented by a type A parity check matrix initial value table is also called 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 called a type B code.

"Type A" and "Type B" designations are based on the ATSC 3.0 standard. For example, ATSC 3.0 employs both type A and type B codes.

Note that DVB-T.2 and others use type B codes.

FIG. 20 is a diagram showing an example of a parity check matrix initial value table for the type B scheme.

That is, FIG. 20 shows a case where the code length N is 16200 bits and the coding rate (coding rate in DVB-T.2 notation) r is 1/4, which is specified in the DVB-T.2 standard. FIG. 10 shows a parity check matrix initial value table (representing parity check matrix H) for type B code.

The check matrix generator 613 (FIG. 18) obtains the check matrix H as follows using the type B system check matrix initial value table.

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

That is, FIG. 21 shows a parity check matrix initial value table for a type B code with a code length N of 16200 bits and a coding rate r of 2/3, which is specified in the DVB-T.2 standard.

The parity check matrix initial value table of the type B method stores the positions of all 1 elements in the information matrix H _A corresponding to the information length K according to the code length N and coding rate r of the LDPC code in 360 columns (parallel factor P), and in the ith row, the row number of the 1 element in the 1+360×(i-1)th column of the parity check matrix H (the row number of the first row of the parity check matrix H is 0) are lined up by the number of column weights of the 1+360×(i−1)th column.

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

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

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

K＝(k+1)×360
... (9)

Here, 360 in equation (9) is the parallel factor P explained in FIG.

In the parity check matrix initial value table of FIG. 21, 13 numerical values are arranged from the 1st to 3rd rows, and 3 numerical values are arranged from the 4th row to the k+1th row (the 30th row in FIG. 21). numbers are lined up.

Therefore, the column weights of the parity check matrix H obtained from the parity check matrix initial value table in FIG. From the (3-1)th column to the Kth column are 3.

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

The second row of the parity check matrix initial value table in FIG. (= 1 + 360 × (2 - 1)) column, row numbers 1, 122, 1516, 3448, 2880, 1407, 1847, 3799, 3529, 373, 971, 4358, 3108 row elements are 1 ing.

As described above, the parity check matrix initial value table represents the position of the 1 element of the information matrix H _A of the parity check matrix H for every 360 columns.

Columns other than the 1+360×(i-1)th column of the check matrix H, that is, each column from the 2+360×(i-1)th column to the 360×ith column are the check matrix initial value table The 1 elements in the 1+360×(i−1)th column determined by are arranged by periodically cyclically shifting downward (downward of the column) according to the parity length M.

That is, for example, the 2+360×(i-1)th column is the 1+360×(i-1)th column cyclically shifted downward by M/360 (=q). , the next 3+360×(i-1)th column is the 1+360×(i-1)th column cyclically shifted downward by 2×M/360 (=2×q) ( 2+360×(i−1)th column is cyclically shifted downward by M/360 (=q)).

Let h _i,j be the number in 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. Let H _wj be the row number of the 1st element in the parity check matrix H. _wj can be obtained by equation (10).

_Hwj = mod(hi _,j + mod((w-1),P) x q, M)
(10)

where mod (x, y) means the remainder of x divided by y.

Also, P is the above-described parallel factor, and in this embodiment, it is 360, for example, like the DVB-T.2 and ATSC 3.0 standards. Furthermore, q is the value M/360 obtained by dividing the parity length M by the parallel factor P (=360).

The check matrix generator 613 (FIG. 18) identifies the row number of the 1 element in the 1+360×(i−1)-th column of the check matrix H from the check matrix initial value table.

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

FIG. 22 is a diagram showing the structure of the parity check matrix H of the type A scheme.

A check matrix for the type A scheme is composed of an A matrix, a B matrix, a C matrix, a D matrix, and a Z matrix.

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

The B matrix is an M1-by-M1 matrix with a staircase structure adjacent to the right of the A matrix.

The C matrix is the adjacent matrix below the A matrix and the B matrix, with N−K−M1 rows and K+M1 columns.

The D matrix is the identity matrix adjacent to the right of the C matrix, with N-K-M1 rows and N-K-M1 columns.

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

In the type A check matrix H composed of the A matrix to D matrix and the Z matrix as described above, part of the A matrix and C matrix constitute an information matrix, and the B matrix, The rest of the C matrix, the D matrix and the Z matrix make up the parity matrix.

Note that the B matrix is a matrix with a staircase structure, and the D matrix is a unit matrix, so part of the parity matrix of the parity matrix H of the type A method (part of the B matrix) has a staircase structure. , the remaining part (part of the D matrix) is a diagonal matrix (identity matrix).

Similar to the information matrix of the check matrix H of the type B method, the A matrix and the C matrix have a cyclic structure for each column of the parallel factor P (for example, 360 columns), and the check matrix initial value table of the type A method represents the position of the 1 element in the A and C matrices every 360 columns.

Here, as described above, part of the A matrix and the C matrix constitute an information matrix, so the type A parity check matrix representing the position of the element of 1 in 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 the 1 element of the information matrix for every 360 columns.

In addition, since the check matrix initial value table of the type A method represents the position of the 1 element in the A matrix and the C matrix for every 360 columns, It can also be said that the position is represented every 360 columns.

FIG. 23 is a diagram showing an example of a parity check matrix initial value table for the type A scheme.

That is, FIG. 23 shows an example of a parity check matrix initial value table representing a parity check matrix H with a code length N of 35 bits and a coding 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 the element of 1 in the A matrix and the C matrix for each parallel factor P, and the ith row contains 1+P×( The row number of the 1 element in the i-1)th column (row number where the row number of the first row of the parity check matrix H is 0) is the column that the 1+P×(i-1)th column has They are lined up by the number of weights.

For simplicity of explanation, the parallel factor P is assumed to be 5, for example.

The parity check matrix H of the type A method has parameters M1, M2, Q1, and Q2.

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 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, the information length K is N × r = 35 × 2/7 = 10, and the parity length M is N - K = 35 - 10 = 25, so M2 is M - M1 = 25 - 15 = 10 becomes.

Q1 is obtained according to the formula Q1=M1/P and represents the shift number (number of rows) of the cyclic shift in the A matrix.

That is, columns other than the 1+P×(i-1)th column of the A matrix of the type A system check matrix H, that is, from the 2+P×(i-1)th column to the P×ith column In each column, the 1 elements in the 1+P×(i-1)th column determined by the parity check matrix initial value table are cyclically shifted downward (toward the bottom of the column) and arranged. and Q1 represents the shift number of that cyclic shift in the A matrix.

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

That is, columns other than the 1+P×(i-1)th column of the C matrix of the check matrix H of the type A method, that is, from the 2+P×(i-1)th column to the P×ith column In each column, the 1 elements in the 1+P×(i-1)th column determined by the parity check matrix initial value table are cyclically shifted downward (toward the bottom of the column) and arranged. and Q2 represents the shift number of that cyclic shift in the C matrix.

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

In the parity check matrix initial value table of 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 parts of the A matrix and the C matrix of the parity check matrix H obtained from the parity check matrix initial value table in FIG. From the 11=1+5×(3−1)th column to the 25=5×5th column, it is 1.

That is, the first row of the parity check matrix initial value table in FIG. It indicates that 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 a matrix of 10 rows and 25 columns (N-K-M1 rows and K+M1 columns), the rows with row numbers 0 to 14 of the parity check matrix H are the rows of the A matrix, and the rows with row numbers 15 to 24 of the parity check matrix H are the rows of the C matrix.

Therefore, among 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 row #18 is the row of the C matrix.

The second row of the parity check matrix initial value table in FIG. It shows that the elements of 2, #10, and #19 are 1.

Here, in the 6th (= 1 + 5 × (2-1)) column of the check matrix H, rows #2 and #10 among rows #2, #10, and #19 are rows of the A matrix , and row #19 is a row of the C matrix.

The third row of the parity check matrix initial value table in FIG. 1.

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

Similarly, 19 in the 4th row of the parity check matrix initial value table in FIG. 15 in the 5th row of the parity check matrix initial value table in FIG. It shows that

As described above, the parity check matrix initial value table represents the positions of the elements of 1 in the A matrix and the C matrix of the parity check matrix H for every parallel factor P=5 columns.

Columns other than the 1+5×(i-1)th column of the A matrix and the C matrix of the check matrix H, that is, each column from the 2+5×(i-1)th column to the 5×ith column are , the 1 element in the 1+5×(i-1)th column determined by the check matrix initial value table is arranged by periodically cyclically shifting downward (downward of the column) according to the parameters Q1 and Q2 It has become a thing.

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

Also, for example, the 2+5×(i-1)th column of the C matrix is obtained by cyclically shifting the 1+5×(i-1)th column downward by Q2 (=2). and the next 3+5×(i-1)th column is the 1+5×(i-1)th column cyclically shifted downward by 2×Q2 (=2×2) ( 2+5×(i−1)th column is cyclically shifted downward by Q2).

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

Then, each column from the 2nd (=2+5×(1-1)) to the 5th (=5+5×(1-1)) column moves down the previous column by Q1=3. is cyclically shifted to

Then, each column from the 7th (=2+5×(2-1)) to the 10th (=5+5×(2-1)) columns moves the previous column down by Q1=3. is cyclically shifted to

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

The parity check matrix generation unit 613 (FIG. 18) uses the parity check matrix initial value table to generate the A matrix, and arranges the stepped B matrix to the right of the A matrix. Then, parity check matrix generation section 613 regards the B matrix as a parity matrix, and performs parity interleaving so that adjacent 1 elements in the B matrix of the staircase structure are separated by a parallel factor P=5 in the row direction.

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

Then, each column from the 2 (= 2 + 5 x (1-1)) to the 5 (= 5 + 5 x (1-1)) columns of the C matrix replaces the previous column with Q2 = 2 is cyclically shifted downward by

Furthermore, in the C matrix of FIG. 26, according to the 2nd to 5th rows of the check matrix initial value table of FIG. 19, row #22 in column 11 (=1+5×(3-1)), row #19 in column 16 (=1+5×(4-1)), and row 21 (=1+5 The element in row #15 of the ×(5-1)) column is 1.

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

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

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

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

After generating the parity check matrix H in FIG. 26, the parity check matrix generation unit 613 regards the D matrix as a parity matrix, and the elements of 1 in the odd-numbered rows and the next even-numbered rows of the unit matrix D matrix are arranged in the row direction. , parity interleave (only the D matrix) such that they are separated by a parallel factor P=5.

FIG. 27 shows the parity interleaving of the D matrix with respect to the parity check matrix H of FIG.

The LDPC encoder 115 (the encoding parity calculation unit 615 (FIG. 18)) performs LDPC encoding (generation of LDPC code) using parity check matrix H in FIG. 27, for example.

Here, the LDPC code generated using the parity check matrix H in FIG. 27 is an LDPC code that performs parity interleaving. Therefore, the LDPC code generated using the parity check matrix H in FIG. There is no need to perform parity interleaving in the parity interleaver 23 (FIG. 9). That is, the LDPC code generated using the check matrix H after parity interleaving of the D matrix is an LDPC code that has undergone parity interleaving. is skipped.

When LDPC encoding is performed using parity check matrix H in FIG. 28 , an LDPC code without parity interleaving is obtained by the LDPC encoding. 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 showing a transformed parity check matrix H obtained by performing row permutation on the parity check matrix H of FIG.

The new LDPC code is an LDPC code with good performance.

Here, an LDPC code with good performance is an LDPC code obtained from an appropriate parity check matrix H.

An appropriate parity check matrix H is, for example, an LDPC code obtained from the parity check matrix H, when transmitted with 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 parity check matrix that satisfies a predetermined condition.

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

Predetermined conditions that an appropriate parity check matrix H should satisfy are, for example, that the analysis result obtained by a code performance analysis method called Density Evolution is good, and that the number of elements of 1, called cycle 4, is good. There is no loop, and so on.

Here, it is known that the decoding performance of the LDPC code is degraded when the information matrix H _A is densely populated with 1 elements like cycle 4. Therefore, the parity check matrix H includes cycles 4 should be absent.

In the parity check matrix H, the minimum value of the loop length (loop length) composed of 1 elements is called girth. Absence of cycle 4 means that girth is greater than 4.

A predetermined condition that an appropriate parity check matrix H should satisfy 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.

86 and 87 are diagrams for explaining density evolution for obtaining analysis results as predetermined conditions that an appropriate parity check matrix H should satisfy.

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

For example, on an AWGN channel, when the noise variance value is increased from 0, the expected value of the error probability of a certain ensemble is 0 at first, but the noise variance value exceeds a certain threshold. Then it will not be 0.

According to Density Evolution, the performance of the ensemble (appropriateness of the parity check matrix) is evaluated by comparing the threshold value of the noise variance value (hereinafter also referred to as the performance threshold) at which the expected value of the error probability is not 0. can decide.

For a specific LDPC code, the ensemble to which the LDPC code belongs is determined, and density evolution is performed on the ensemble to roughly predict the performance of the LDPC code.

Therefore, if an ensemble with good performance is found, an LDPC code with good performance can be found among the LDPC codes belonging to that ensemble.

Here, the above-mentioned degree sequence represents the proportion of variable nodes and check nodes having weights of respective values with respect to the code length N of the LDPC code.

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

Figure 86 shows the Tanner graph of such an ensemble.

In the Tanner graph of FIG. 86, there are N variable nodes indicated by circles (○) in the figure equal to the code length N, and check nodes indicated by squares (□) in the figure have the code length N and the coding rate There are N/2 equal to the product multiplied by 1/2.

Each variable node has 3 edges connected to it equal to the column weight, so there are a total of 3N edges connecting to N variable nodes.

Also, each check node has 6 branches connected to it equal to the row weight, so there are a total of 3N branches connecting to N/2 check nodes.

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

The interleaver randomly permutes the 3N branches connected to N variable nodes, and converts each permuted branch to one of the 3N branches connected to N/2 check nodes. Connect to one of us.

There are (3N)! (= (3N) x (3N-1) x ... x 1) permutation patterns for permuting 3N branches connected to N variable nodes in the interleaver. There is only Therefore, an ensemble characterized by degree-leakage 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.

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

In the multi-edge type, the interleaver through which the branches connecting to the variable nodes and the branches connecting to the check nodes go through is divided into multiple (multi-edge), which makes the characterization of the ensemble more strictly done.

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

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

Also, in the Tanner graph of FIG. 87, there is only v1 variable node with one branch connected to the first interleaver, zero branch connected to the second interleaver, and one branch connected to the first interleaver. , only v2 variable nodes with 2 branches leading to the second interleaver, v3 variable nodes with 0 branches leading to the first interleaver and 2 branches leading to the second interleaver, respectively exist.

Furthermore, in the Tanner graph of FIG. 87, there are 2 branches connected to the first interleaver, there are only c1 check nodes with 0 branches connected to the second interleaver, and there are 2 branches connected to the first interleaver. , c2 check nodes with 2 branches leading to the second interleaver, c3 check nodes with 0 branches leading to the first interleaver and 3 branches leading to the second interleaver, respectively. exist.

Here, regarding density evolution and its implementation, see, for example, "On the Design of Low-Density Parity-Check Codes within 0.0045 dB of the Shannon Limit", S.Y.Chung, G.D.Forney, T.J.Richardson,R.Urbanke, IEEE Communications Leggers, VOL.5, NO.2, Feb 2001.

In the simulation for (the check matrix of) the new LDPC code, the BER starts to drop (becomes smaller) due to multi-edge type density evolution, E _b /N ₀ (signal power to noise power ratio per bit). A performance threshold finds an ensemble with a predetermined value or less, and among the LDPC codes belonging to the ensemble, an LDPC code that reduces the BER when using one or more orthogonal modulations such as QPSK is selected as a high-performance LDPC code. Selected.

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

Therefore, according to the new LDPC code, it is possible to ensure good communication quality in data transmission.

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

Also, for the parity check matrix H of the type A code, the column weight of the 1st to M1−1 columns of the B matrix is 2, and the column weight of the M1th column (the last column) of the B matrix is 1. Furthermore, the column weight of the D matrix is 1 and the column weight of the Z matrix is 0.

<Constellation>

98 to 122 are diagrams showing examples of constellations that can be employed in the transmission system of FIG. 7. FIG.

In the transmission system of FIG. 7, for example, a constellation to be used in 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.

Constellations include UC (Uniform Constellation) in which signal points are arranged uniformly and NUC (Non Uniform Constellation) in which the arrangement of signal points is not uniform.

In addition, 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). ration, etc.

In general, 1D-NUC improves BER more than UC, and 2D-NUC improves BER more than 1D-NUC.

A constellation whose modulation method is QPSK becomes UC. As a constellation with a modulation method of 16QAM, 64QAM, 256QAM, etc., for example, UC or 2D-NUC can be adopted. -NUC can be adopted.

In the transmission system of FIG. 7, for example, a constellation specified by ATSC3.0, 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.

Also, 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.

Also, 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, QPSK UC is also described as QPSK-UC, and 2 ^m QAM UC is also described as 2 ^m QAM-UC. 2 ^m QAM 1D-NUC and 2D-NUC are also described as 2 ^m QAM-1D-NUC and 2 ^m QAM-2D-NUC, respectively.

Some of the constellations specified in ATSC 3.0 are described below.

FIG. 98 is a diagram showing 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 _zs " represents the coordinates of signal point _zs . Note that the index _s of the signal point zs (the same applies to the index _q of the signal point zq, which will be 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 _zs are represented in the form of complex numbers, and j represents the imaginary unit (√(-1)).

FIG. 99 shows the coding rate r(CR) of the LDPC code specified by ATSC3.0 when the modulation scheme is 16QAM = 2/15, 3/15, 4/15, 5/15, 6/ 15, 7/15, 8/15, 9/15, 10/15, 11/15, 12, 15, and 13/15 are diagrams showing coordinates of signal points of 16QAM-2D-NUC used; FIG.

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

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

In the 2D-NUC, the signal points in the 2nd quadrant of the constellation are placed in positions symmetrically shifted from the signal points in the 1st quadrant with respect to the Q-axis, and the signal points in the 3rd quadrant of the constellation are placed in the 3rd quadrant. The signal points of one quadrant are arranged at positions shifted symmetrically with respect to the origin. Then, the signal points in the fourth quadrant of the constellation are arranged at positions shifted symmetrically with respect to the I axis from the signal points in the first quadrant.

Here, when the modulation scheme is 2 ^m QAM, m bits are defined as one symbol, and that one symbol is mapped to the signal point corresponding to that symbol.

For example, an ^m -bit symbol can be represented by an ^{integer value from 0 to 2 m -1} . y(0), ^y (1), . 2b) to y(3b-1) and y(3b) to y(4b-1).

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

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

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

For example, if the modulation scheme is 16QAM, m= ⁴ -bit symbols y(0), y(1), . It is classified into four categories: (0) to y(3), y(4) to y(7), y(8) to y(11), and y(12) to y(15).

Then, among the symbols y(0) to y(15), for example, the symbol y(12) is the symbol y(k+3b)=y( 0+3×4) and k=0, the coordinates of the signal point corresponding to symbol y(12) are -w#k=-w0.

Now, assuming that the coding rate r(CR) of the LDPC code is, for example, 9/15, according to FIG. 99, w0 is 0.2386+j0.5296, so the coordinate -w0 of the signal point corresponding to symbol y(12) is -(0.2386+j0.5296).

FIG. 100 shows the coding rate r(CR) of the LDPC code specified by ATSC3.0 when the modulation scheme is 1024QAM=2/15, 3/15, 4/15, 5/15, 6/ 15, 7/15, 8/15, 9/15, 10/15, 11/15, 12, 15, and 13/15 are diagrams showing examples of coordinates of signal points of 1024QAM-1D-NUC. .

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

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

Now, let's take a 1024QAM 10-bit symbol y from its leading bit (most significant bit) as y0,s, y1, _s , y2 _{, s} , y3 _,s , y4 _,s , y5 _{, s} , y6 _,s , y7 _,s , y8 _,s , and y9 _,s .

FIG. 101A shows five even-numbered bits y1 _,s , y3 _,s , y5 _,s , y7 _,s , y9 _,s of symbol y and signal point _zs corresponding to symbol y. , which represents the correspondence with u#k representing the (coordinate) real part Re(z _s ).

B in FIG. 101 shows five odd-numbered bits y _0,s , y _2,s , y _4,s , y _6,s , y _8,s of symbol y and signal point z _s corresponding to symbol y. represents the correspondence with u#k representing the imaginary part Im(z _s ) of .

1024QAM 10-bit symbol y = (y0 _,s , y1,s, y2,s, y3,s, y4, _s , y5, _s , y6 _{, s} , _{y7 , 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 even-numbered 5 bits (y _1,s , y _3,s , y5,s, y7 _{, s} , y9 _,s ) are (0,0,1,1,0).

In A of FIG. 101, even-numbered 5 bits (0,0,1,1,0) are associated with u11, so 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, so symbol y=(0,0,1,0,0,1, 1,1,0,0), the imaginary part Im(z _s ) of the signal point z _s is u3.

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

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

In the constellation, the signal points of the 1D-NUC are arranged in a grid on straight lines parallel to the I axis and straight lines parallel to the Q axis. However, the intervals between signal points are not constant. Also, in transmitting (data mapped to) signal points, the average power of the signal points on the constellation can be normalized. _Let P _ave be the mean square of the absolute values of all signal points (coordinates) on the constellation _. P _ave ) can be done by multiplying each signal point z _s on the constellation.

The transmission system of FIG. 7 can use the constellation defined by ATSC 3.0 as described above.

<Block Interleaver 25>

FIG. 123 is a diagram for explaining block interleaving performed by block interleaver 25 in FIG.

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

Let Npart1 be the length (number of bits) of part 1, and Npart2 be the length of part 2. Npart1+Npart2 is equal to the code length N.

Conceptually, in block interleaving, the column (vertical) direction as one direction is a storage area for storing Npart1/m bits, and the row direction orthogonal to the column direction is the number of bits of a symbol. Arranged by a number m equal to m, each column is partitioned from above into 360-bit subunits with a parallel factor P. This small column unit is also called a column unit.

In block interleaving, as shown in FIG. 123, writing part 1 of the LDPC code of one codeword from the top to the bottom (column direction) of the first column unit of the column is equivalent to writing from the left to the right column. It is done towards

Then, when the writing to the first column unit of the rightmost column is completed, as shown in FIG. Part 1 of the LDPC code of one codeword is written in the same manner, starting from the rightward column.

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

This m-bit unit of part 1 is provided from block interleaver 25 to mapper 117 (FIG. 8) as an m-bit symbol.

Part 1 is read in units of m bits, starting from the bottom row of m columns. is supplied from the block interleaver 25 to the mapper 117 as symbols of .

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

Npart1/m, the column length, is a multiple of 360, which is the parallel factor P, so that Npart1/m is a multiple of 360, a one-codeword LDPC code has part 1 and part 2 can be divided into

FIG. 124 is a diagram showing an example of Part 1 and Part 2 of an LDPC code with a code length N of 69120 bits for each of QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM modulation schemes.

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

<Groupwise interleave>

FIG. 125 is a diagram explaining the groupwise interleaving performed by the groupwise interleaver 24 of FIG.

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

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

When the parallel factor P is 360, for example, an LDPC code with 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 with a code length N of 69120 bits is divided into 192 (=69120/360) bit groups of bit groups 0, 1, .

Also, hereinafter, the GW pattern is represented by a sequence of numbers representing bit groups. For example, for an LDPC code of 5 bit groups 0,1,2,3,4 with a code length N of 1800 bits, for example, the GW pattern 4,2,0,3,1 is for bit groups 0,1, It represents interleaving (permuting) the sequence of 2, 3, 4 into the sequence of bit groups 4, 2, 0, 3, 1.

For example, let x _i be the i+1-th code bit from the beginning of an LDPC code with a code length N of 1800 bits.

In this case, according to the group-wise interleaving of the GW pattern 4,2,0,3,1, the 1800-bit LDPC code _{ x0,x1,..., _{x1799 }} is represented by { _x1440 , _x1441 , ...,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 is for each code length N of the LDPC code, each coding rate r, each modulation scheme, each constellation, and two or more of the code length N, coding rate r, modulation scheme, and constellation. It can be set for each combination.

<Configuration example of receiving device 12>

FIG. 137 is a block diagram showing a configuration example of the receiving device 12 in FIG.

An OFDM processing unit (OFDM operation) 151 receives an OFDM signal from the transmission device 11 (FIG. 7) and performs signal processing on the OFDM signal. Data obtained by signal processing performed by the OFDM processing unit 151 is supplied to a frame management unit (Frame Management) 152 .

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

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

The demapper 154 demaps the data (data on the constellation) from the frequency deinterleaver 153 based on the signal point arrangement (constellation) determined by the quadrature modulation performed on the transmitter 11 side. decoding) and orthogonal demodulation, and the resulting data (LDPC code (likelihood of)) is supplied to an LDPC decoder 155 .

The LDPC decoder 155 performs LDPC decoding of the LDPC code from the demapper 154 and supplies the resulting LDPC target data (BCH code here) to the BCH decoder 156 .

The BCH decoder 156 performs BCH decoding on 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 frequency deinterleaves the data from the frame management unit 152 on a symbol-by-symbol basis, and supplies the data to the SISO/MISO decoder (SISO/MISO decoder) 162 .

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

A time deinterleaver 163 time-deinterleaves the data from the SISO/MISO decoder 162 on a symbol-by-symbol basis and supplies it to a demapper 164 .

The demapper 164 demaps the data from the time deinterleaver 163 (data on the constellation) based on the signal point arrangement (constellation) determined by the orthogonal modulation performed on the transmitter 11 side. decoding) and orthogonal demodulation, and the resulting data is supplied to a bit deinterleaver 165 .

The bit deinterleaver 165 bit deinterleaves the data from the demapper 164 and supplies the LDPC code (likelihood thereof), which 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 the resulting LDPC target data (BCH code here) to the BCH decoder 167 .

The BCH decoder 167 performs BCH decoding of the LDPC target data from the LDPC decoder 155 and supplies the resulting data to a BB descrambler (BB DeScrambler) 168 .

The BB descrambler 168 applies BB descramble to the data from the BCH decoder 167 and supplies the resulting data to a null deletion unit (Null Deletion) 169 .

A null deletion unit 169 deletes the nulls inserted by the padder 112 in FIG.

The demultiplexer 170 separates one or more streams (target data) multiplexed on the data from the null removal unit 169, performs necessary processing, and outputs as an output stream.

Note that the receiving device 12 can be configured without some of the blocks shown in FIG. That is, for example, when the transmitting device 11 (FIG. 8) is configured without the time interleaver 118, the SISO/MISO encoder 119, the frequency interleaver 120, and the frequency interleaver 124, the receiving device 12 A time deinterleaver 163, a SISO/MISO decoder 162, and a frequency deinterleaver 161, which are blocks corresponding to the time interleaver 118, SISO/MISO encoder 119, frequency interleaver 120, and frequency interleaver 124 of the transmission device 11, respectively. , and can be configured without the frequency deinterleaver 153 .

<Configuration example of bit deinterleaver 165>

That is, the block deinterleaver 54 performs block deinterleaving corresponding to the block interleaving performed by the block interleaver 25 in FIG. Block deinterleaving is performed to return the positions of (the likelihood of) the code bits of the LDPC code rearranged by interleaving to their original positions, and the resulting LDPC code is supplied to the groupwise deinterleaver 55 .

The group-wise deinterleaver 55 performs group-wise deinterleaving corresponding to the group-wise interleaving performed by the group-wise interleaver 24 in FIG. That is, for example, the code bits of the LDPC code whose arrangement has been changed in bit group units by the groupwise interleaving described with reference to FIG.

Here, when the LDPC code supplied from the demapper 164 to the bit deinterleaver 165 is subjected to parity interleaving, groupwise interleaving, and block interleaving, the bit deinterleaver 165 performs parity interleaving corresponding to the parity interleaving. De-interleaving (reverse processing of parity interleaving, i.e., parity de-interleaving to restore the code bits of the LDPC code reordered by parity interleaving), block de-interleaving corresponding to block interleaving, and group-wise interleaving can do all of the group-wise deinterleaving corresponding to .

However, in the bit deinterleaver 165 of FIG. 138, the block deinterleaver 54 that performs block deinterleaving corresponding to block interleaving and the groupwise deinterleaver 55 that performs groupwise deinterleaving corresponding to groupwise interleaving are: However, no parity deinterleaving block corresponding to the parity interleaving is provided and no parity deinterleaving is performed.

Therefore, from the bit deinterleaver 165 (the groupwise deinterleaver 55 of) to the LDPC decoder 166, block deinterleaving and groupwise deinterleaving are performed, and parity deinterleaving is not performed LDPC code is supplied.

The LDPC decoder 166 performs LDPC decoding of the LDPC code from the bit deinterleaver 165 with respect to the parity check matrix H of the type B scheme used for the LDPC encoding by the LDPC encoder 115 in FIG. and the transformation check matrix (Fig. 29) obtained by performing row permutation on the type A check matrix (Fig. 27). Output as the result of data decoding.

FIG. 139 is a flow chart illustrating the processing performed by the demapper 164, bit deinterleaver 165, and LDPC decoder 166 of FIG.

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

In step S112, the bit deinterleaver 165 deinterleaves (bit deinterleaves) the 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 (symbols) from the demapper 164, and the code bits of the resulting LDPC code are grouped. It is supplied to the wise deinterleaver 55 .

The group-wise deinterleaver 55 performs group-wise deinterleaving on the LDPC code from the block deinterleaver 54 and supplies the resulting LDPC code (likelihood thereof) to the LDPC decoder 166 .

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

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

Also, if the transmitting device 11 does not perform group-wise interleaving, the receiving device 12 can be configured without the group-wise deinterleaver 55 that performs group-wise deinterleaving.

<LDPC decoding>

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

In the LDPC decoder 166 of FIG. 137, as described above, block deinterleaving and groupwise deinterleaving from the groupwise deinterleaver 55 are performed, and parity deinterleaving is not performed LDPC of the LDPC code For decoding, the parity check matrix H of the type B scheme used for LDPC encoding by the LDPC encoder 115 in FIG. This is performed using a transformation check matrix (FIG. 29) obtained by performing row permutation on the matrix (FIG. 27).

Here, LDPC decoding has been previously proposed, in which it is possible to suppress the operating frequency within a sufficiently feasible range while suppressing the circuit scale by performing LDPC decoding using a transform parity check matrix (for example, , see Patent No. 4224777).

Therefore, first, the previously proposed LDPC decoding using a transform parity check matrix will be described with reference to FIGS. 140 to 143. FIG.

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

In addition, 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 showing parity check matrix H′ obtained by performing row permutation of equation (11) and column permutation of equation (12) on parity check matrix H of FIG.

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

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

However, in 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 is.

According to the row permutation of equation (11), the 1st, 7th, 13th, 19th and 25th rows, which are divided by 6 and have a remainder of 1, are the 1st, 2nd, 3rd, 4th and 5th rows, respectively. The 2nd, 8th, 14th, 20th and 26th rows, which have a remainder of 2 when divided, are replaced with the 6th, 7th, 8th, 9th and 10th rows, respectively.

Further, according to the column permutation of equation (12), the 61st, 67th, 73rd, 79th, and 85th columns, which have a remainder of 1 when divided by 6, are respectively 61 , the 62nd, 63rd, 64th, and 65th columns, and the 62nd, 68th, 74th, 80th, and 86th columns that have a remainder of 2 when divided by 6 are the 66th, 67th, 68th, 69th, and 70th columns, respectively. Substitutions are made accordingly.

In this way, a matrix obtained by permuting the rows and columns of the parity check matrix H of FIG. 140 is the parity check matrix H' of FIG.

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

In addition, the column permutation of equation (12) is the above-described parity interleaving that interleaves the K + qx + y + 1th code bit at the position of the K + Py + x + 1th code bit, and the information length is K is 60, the parallel factor P is 5, and the divisor q (=M/P) of the parity length M (here, 30) is 6, respectively.

Therefore, the parity check matrix H' in FIG. is a transformed parity check matrix obtained by performing at least column permutation to replace the columns of .

When the transformed parity check matrix H′ of FIG. 141 is multiplied by the LDPC code of the original parity check matrix H of FIG. 140 that has undergone the same permutation as in Equation (12), a 0 vector is output. That is, if the row vector c obtained by applying the column permutation of equation (12) to the row vector c as the LDPC code (one codeword) of the original check matrix H is denoted by c′, then from the properties of the check matrix , Hc ^T is a 0 vector, so H'c' ^T is also a 0 vector.

141 is the parity check matrix of the LDPC code c' obtained by performing the column permutation of Equation (12) on the LDPC code c of the original parity check matrix H. FIG.

Therefore, the LDPC code c of the original parity check matrix H is subjected to the column permutation of Equation (12), and the LDPC code c' after the column permutation is decoded using the transform parity check matrix H' of FIG. 141 (LDPC decoding). Then, by performing the inverse permutation of the column permutation of Equation (12) on the decoding result, the same decoding result as when the LDPC code of the original parity check matrix H is decoded using the parity check matrix H can be obtained. can be done.

FIG. 142 is a diagram showing the transform parity check matrix H′ of FIG. 141 spaced in units of 5×5 matrices.

In FIG. 142, the transformation parity check matrix H′ is a 5×5 (=P×P) identity matrix that is the parallel factor P, and a matrix in which one or more of the 1s of the identity matrix are 0 (hereinafter referred to as appropriate , quasi-identity matrix), a matrix obtained by cyclically shifting the identity matrix or quasi-identity matrix (hereinafter referred to as a shift matrix as appropriate), the sum of two or more of the identity matrix, the quasi-identity matrix, or the shift matrix (hereinafter referred to as a sum matrix as appropriate), which is represented by a combination of 5×5 0 matrices.

It can be said that the transformation parity check matrix H′ in FIG. 142 is composed of a 5×5 identity matrix, a quasi-identity matrix, a shift matrix, a sum matrix, and a 0 matrix. Therefore, these 5×5 matrices (identity matrix, quasi-identity matrix, shift matrix, sum matrix, zero matrix) that constitute the transform check matrix H′ are hereinafter referred to as constituent matrices as appropriate.

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

Data are stored in the third to ninth storage areas in association with the transformation parity check matrix H'.

The FIFOs 300 ₃ to 300 ₆ also store data in association with the conversion parity check matrix H′.

The branch data storage memory 304 is composed of 18 FIFOs 304 ₁ to 304 ₁₈ obtained by dividing the 90 columns of the transform parity check matrix H' by 5, which is the number of columns of the component matrix (parallel factor P). The FIFO 304 _x (x=1, 2, . . . , 18) consists of a plurality of stages of storage areas. Messages corresponding to one branch can be read and written at the same time.

That is, the first storage area of the FIFO 304 ₁ stores the data corresponding to the position of 1 in the 5×5 identity matrix from (1,1) to (5,5) of the transformation parity check matrix H′. . In the storage area of the second stage, the sum matrix of (6,1) to (10,5) of the transformation check matrix H' (the first shift obtained by cyclically shifting the 5×5 identity matrix by one The data corresponding to the position of 1 in the first shift matrix constituting the sum matrix, which is the sum of the matrix and the second shift matrix cyclically shifted by two to the right, is stored.

Similarly, the FIFOs 304 ₁₃ to 304 ₁₈ store data in association with the transform parity check matrix H', each having a length of two.

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

The branch data storage memory 300 consists of six FIFOs 300 ₁ to 300 ₆ , and indicates to which row of the transform parity check matrix H′ in FIG. 142 the five messages D311 supplied from the preceding cyclic shift circuit 308 belong. According to information (matrix data) _D312 , a FIFO for storing data is selected from among FIFOs 3001 to 3006, and _five messages D311 are collectively stored in the selected FIFO in order. When reading data, the branch data storage memory 300 sequentially reads _five messages _D3001 from the FIFO 3001 and supplies them to the selector 301 in the next stage. After reading the messages from the FIFO 300 ₁ , the branch data storage memory 300 sequentially reads the messages from the FIFOs 300 ₂ to 300 ₆ and supplies them to the selector 301 .

The selector 301 selects five messages from the FIFOs from which data is currently being read out of the FIFOs 300 ₁ to 300 ₆ according to the select signal D301, and supplies them to the check node calculator 302 as messages D302.

The check node calculator 302 consists of five check node calculators 302 ₁ to 302 ₅ , and uses messages D302 (D302 ₁ to D302 ₅ ) (messages v _i in equation (7)) supplied through the selector 301 to A check node operation is performed according to equation (7), and five messages D303 (D303 ₁ to D303 ₅ ) obtained as a result of the check node operation (messages u _j in equation (7)) are supplied to the cyclic shift circuit 303 .

The cyclic shift circuit 303 shifts the five messages D303 ₁ through D303 ₅ obtained by the check node calculation unit 302 by the number of unit matrices (or quasi-unit matrices) whose corresponding branches are the originals in the transform parity check matrix H′. Based on the information (matrix data) D305 as to whether it has been click-shifted, cyclic shift is performed, and the result is supplied to the branch data storage memory 304 as a message D304.

The branch data storage memory 304 consists of 18 FIFOs 304 ₁ to 304 ₁₈ , and according to the information D 305 to which row of the conversion check matrix H′ the five messages D 304 supplied from the preceding cyclic shift circuit 303 belong. , a FIFO for storing data is selected from FIFOs 304 ₁ to 304 ₁₈ , and five messages D304 are collectively stored in the selected FIFO in order. When reading data, the branch data storage memory 304 sequentially reads _five messages _D3061 from the FIFO 3041 and supplies them to the selector 305 in the next stage. After reading data from the FIFO 304 ₁ , the branch data storage memory 304 sequentially reads messages from the FIFOs 304 ₂ to 304 ₁₈ and supplies them to the selector 305 .

The selector 305 selects five messages from the FIFOs from which data is currently being read out of the FIFOs 304 ₁ to 304 ₁₈ according to the select signal D307, and outputs them as messages D308 from the variable node calculator 307 and the decoded word calculator. 309.

On the other hand, received data rearrangement section 310 rearranges LDPC code D313 corresponding to parity check matrix H in FIG. It is supplied to the received data memory 306 . Received data memory 306 calculates and stores received LLRs (logarithmic likelihood ratios) from received data D314 supplied from received data rearrangement section 310, and collects the received LLRs by five as received value D309. , to the variable node calculator 307 and the decoded word calculator 309 .

The variable node calculator 307 consists of five variable node calculators 307 ₁ to 307 ₅ , and receives messages D308 (D308 ₁ to D308 ₅ ) (messages u _j in equation (1)) supplied through the selector 305 and received data Using the five received values D309 (received value u _0i of equation (1)) supplied from memory 306 for variable node calculation according to equation (1), messages D310 (D310 ₁ to D310 ₅ ) (message v _i in equation (1)) to the cyclic shift circuit 308 .

Based on the information as to whether or not the data has been cyclically shifted, the result is supplied to the branch data storage memory 300 as a message D311.

One cycle of decoding (variable node operation and check node operation) of the LDPC code can be performed by repeating the above operations. After decoding the LDPC code a predetermined number of times, the decoding device in FIG. 143 obtains and outputs the final decoding result in decoded word calculation section 309 and decoded data rearrangement section 311 .

That is, the decoded word calculator 309 is composed of five decoded word calculators 309 ₁ to 309 ₅ , and five messages D308 (D308 ₁ to D308 ₅ ) output by the selector 305 (message u _j in equation (5)) and , using the five received values D309 (received values u _0i in equation (5)) supplied from the received data memory 306, and as the final stage of decoding multiple times, based on equation (5), the decoding result (decoding word), and the resulting decoded data D315 is supplied to the decoded data rearrangement unit 311.

The decoded data rearrangement unit 311 performs inverse permutation of the column permutation of equation (12) on the decoded data D315 supplied from the decoded word calculation unit 309, thereby rearranging the order, and the final decoding result Output as D316.

As described above, one or both of row permutation and column permutation are applied to the parity check matrix (original parity check matrix), and one or more of the 1s of the P × P unit matrix and its elements are changed to 0. A quasi-identity matrix, a shift matrix obtained by cyclically shifting an identity matrix or a quasi-identity matrix, a sum matrix that is the sum of multiple identity matrices, quasi-identity matrices, or shift matrices, a combination of P×P zero matrices, that is, By converting to a parity check matrix (transformation parity check matrix) that can be represented by a combination of component matrices, decoding of LDPC codes can be performed by performing check node operation and variable node operation with P It is possible to adopt an architecture in which they are performed simultaneously. When adopting an architecture that simultaneously performs P node operations (check node operations and variable node operations), the number of which is smaller than the number of rows and columns of the parity check matrix, the number of node operations equal to the number of rows and columns of the parity check matrix is used. As compared with the case of simultaneously performing multiple iterations, a large number of iterative decoding operations can be performed while keeping the operating frequency within a feasible range.

The LDPC decoder 166 forming the receiving device 12 in FIG. 137 performs LDPC decoding by performing P check node calculations and P variable node calculations at the same time, for example, like the decoding device in FIG.

That is, to simplify the explanation, the parity matrix of the LDPC code output by the LDPC encoder 115 constituting the transmitting device 11 in FIG. parity interleaver 23 of the transmitting device 11 performs parity interleaving for interleaving the K+qx+y+1-th code bit into the position of the K+Py+x+1-th code bit. is performed by setting the information length K to 60, the parallel factor P to 5, and the divisor q (=M/P) of the parity length M to 6, respectively.

Since this parity interleaving corresponds to the column permutation of equation (12) as described above, the LDPC decoder 166 does not need to perform the column permutation of equation (12).

Therefore, in the receiving device 12 of FIG. 137, as described above, the groupwise deinterleaver 55 sends the LDPC code to the LDPC decoder 166 for which parity deinterleaving has not been performed, that is, the sequence of equation (12). A permuted LDPC code is supplied, and the LDPC decoder 166 performs the same processing as the decoding device in FIG. 143, except that the column permutation of equation (12) is not performed.

144 is a diagram showing a configuration example of the LDPC decoder 166 of FIG. 137. In FIG.

144, LDPC decoder 166 is configured in the same manner as the decoding device in FIG. 143 except that received data rearrangement section 310 in FIG. 143 is performed except that the decoder is not encoded, the description thereof will be omitted.

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

140 to 144, in order to simplify the 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, respectively, but the code length N, the information length K, the parallel factor P, and the divisor q (=M/P) are respectively It is not limited to values.

That is, in the transmission device 11 of FIG. 8, the LDPC encoder 115 outputs, for example, the code length N of 64800, 16200, 69120, etc., the information length K of N-Pq (= N-M), the parallel factor P is 360, and the divisor q is M/P, respectively. The LDPC decoder 166 in FIG. Therefore, it can be applied to LDPC decoding.

Further, after the LDPC code is decoded by the LDPC decoder 166, the parity part of the decoding result is unnecessary, and only the information bits of the decoding result are output. can be configured.

<Configuration example of block deinterleaver 54>

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

In the block deinterleaving, the sequence of code bits of the LDPC code is restored (restored) to the original sequence by performing processing opposite to the block interleaving of the block interleaver 25 described with reference to FIG. 123 .

That is, in block deinterleaving, for example, similarly to block interleaving, the LDPC code is written to and read from m columns equal to the number of bits of the symbol m, so that the code bit sequence 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. Furthermore, in block deinterleaving, reading of LDPC codes is performed in the order in which the LDPC codes are written in block interleaving.

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

Part 1 writes in units of m bits are performed sequentially toward the row below m columns, and when the part 1 write is completed, as shown in FIG. , reading part 1 downwards from left to right in columns.

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

When part 1 of the 1-codeword LDPC code is read out, the m-bit symbol unit of part 2, which has an m-bit symbol unit, is sequentially concatenated after part 1, whereby the symbol unit is returned to the code bit array of the original 1-codeword LDPC code (the LDCP code before block interleaving).

<Another configuration example of the bit deinterleaver 165>

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

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

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

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