  • the present invention relates to the field of communications technologies, and in particular, to a data processing method and apparatus.
  • the transmitting end of the digital communication system usually includes a source, a channel coder and a modulator.
  • the receiving end usually includes a demodulator, a channel decoder and a sink.
  • a schematic diagram of a digital communication system in the prior art is shown in FIG.
  • the channel coder is used to introduce information bits into the information bits according to certain rules so that the receiving channel decoder can correct the errors occurring when the information is transmitted on the channel to some extent. Therefore, channel coding is a Forward Error Correction (FEC) technique.
  • FEC Forward Error Correction
  • FEC coding is a process of generating a check bit sequence from an information bit sequence, and the information bit sequence and the check bit sequence together constitute a commonly known code word bit sequence.
  • Commonly used FEC codes include Turbo codes, Low Density Parity Check Codes (LDPCs), and convolutional codes.
  • LDPCs Low Density Parity Check Codes
  • Turbo codes are used for data transmission in LTE systems; IEEE 802.11 systems are used. It is an LDPC code and a convolutional code.
  • Polar code is a new star in the coding field. It is a linear channel coding method proposed by Professor Erdal Arikan of the University of Birken University in Turkey based on channel polarization theory in 2008. The code word is the only one discovered so far that can reach the Shannon limit. The encoding method. The core idea of the Polar code is the channel polarization theory, and the polarization methods corresponding to different channels will be different.
  • the binary turbo coding of LTE is a parallel concatenated code with an internal interleaver, which is generally formed by parallel concatenation of two recursive system convolutional code (RSC) component code encoders having the same structure.
  • the decoder of the turbo code is also composed of two cascaded sub-decoders, a first component decoder and a second component decoder, respectively.
  • the LDPC code is a linear block code based on a sparse check matrix. By using the sparsity of its check matrix, low-complexity codecs can be realized.
  • LDPC code decoding can be based on Iterative algorithm of belief propagation (referred to as the letter transmission algorithm).
  • the convolutional code is another commonly used FEC code.
  • the characteristic of the convolutional code is that when the input information of a certain time is encoded, the output is determined not only according to the input of the current time but also according to the input of the p times before the current time.
  • the codewords ie the generation of codewords, are subject to a total of p+1 input moments.
  • a convolutional code is a finite state machine whose encoding and decoding can be analyzed by means of a grid map. The basic idea of decoding the convolutional code is based on the received codeword, calculating its distance from all other possible continuous grid paths one by one, and selecting the one with the most possibility as the decoded estimate. .
  • the decoding methods of the various FEC codes described above can obtain decoded estimates of codeword bits or information bits. However, if the result of the decoding is correct, it needs to be detected by some means of error detection.
  • CRC Cyclic Redundancy Check Code
  • the CRC code consists of two parts.
  • the first part is the information code, that is, the information to be verified, and the latter part is the check code. If the CRC code is a total of n bits and the information code is k bits long, it is called a (n, k) code.
  • the generator polynomial should satisfy the following principles: 1) the highest and lowest bits of the generator polynomial must be 1; 2) when any error occurs in any of the transmitted information (CRC code), the generator polynomial is used to perform modulo 2 division. After that, the remainder should not be 0; 3) When the error occurs in different bits, the remainder should be different; 4) If the remainder continues to be modulo 2, the remainder should be cycled.
  • the basic principle of CRC error detection is: first, for a given set of information data and a generator polynomial, a remainder of the characteristic length can be obtained by calculation, and the remainder is attached to the information data and then sent together; then the receiving end receives the passing After the CRC verified data, the information bits and the check bits are separated; the comparison information bits are separated from the receiving end by the remainder of the local generated polynomial. If the check digits are the same, it is determined that the received data is correct.
  • CRC codes are widely used in various communication systems.
  • the CRC code is used extensively from the physical layer to the upper layer to verify the correctness of the data.
  • the physical layer data sharing channel is transmitted by using a Transmission Block (TB) as a basic unit.
  • TB Transmission Block
  • the receiving end determines whether the current TB is correctly received through the cyclic redundancy check code (CRC) of the TB. If the TB is correctly received, the receiving end feeds back an ACK message to the transmitting end; if the TB does not receive correctly, the receiving end feeds back a NACK message to the transmitting end.
  • CRC cyclic redundancy check code
  • the LTE specification lists all code block sizes that can be supported, ranging from a minimum of 40 bits to a maximum of 6114 bits.
  • code block splitting is required before Turbo coding.
  • a larger TB can also be divided into multiple equal-sized Code Block Sets (CBSs), and each code block set is composed of multiple code blocks.
  • CBSs Code Block Sets
  • LTE introduces the possibility of inserting padding bits in the first code block header.
  • the transport block size defined in current LTE is chosen so that padding bits are generally not required.
  • the code block partitioning and CRC insertion including the code block set are as shown in FIG.
  • the data channel adopts a two-level CRC data check mode, which is a Code Block (CB) CRC and a Transport Block (TB) CRC. Both CRCs are 24 bits in length but differ in the generator polynomial.
  • CB Code Block
  • TB Transport Block
  • Both CRCs are 24 bits in length but differ in the generator polynomial.
  • the large transport block TB is subjected to CRC check using the root generator polynomial g CRC24A (D), and then the code block CB is subjected to CRC check using g CRC24B (D). among them:
  • a small data packet usually refers to data of a single TB block having a length of several tens to several hundreds of bits.
  • the short code as above still adds a 24-bit transport block CRC in the Turbo code-based data communication, the direct result is that the 24-bit CRC can provide good error detection performance.
  • Larger redundancy rate which reduces the transmission efficiency of the wireless channel.

Therefore, it is very important to choose the CRC length reasonably to meet the false detection rate requirement of the actual system and to properly improve the transmission efficiency.
