Embodiment Construction

[0041] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the present disclosure. However, it will be understood by those skilled in the art that the present disclosure may be practiced without these specific details.

[0042] The embodiment of the present disclosure provides a data processing method 100 based on QC_LDPC codes. For ease of understanding, the following combination Figure 2-Figure 15 , to describe the method in detail.

[0043] Such as figure 2 As shown, it is the whole process of one of the traditional 5G NR LDPC channel coding. At the sending end of the data, before LDPC code encoding, it is necessary to determine the encoding parameters, including TBS (transmit block size, transmission block size) size, segmentation or not, and BG parameters. Wherein, the TBS obtains one or more code blocks after the segmentation step. After LDPC encoding, rate matching, bit interle...

Abstract

The embodiment of the invention provides a data processing method based on a QC_LDPC code, a communication device, network equipment and a storage medium. The data processing method comprises the steps: inputting a first QC_LDPC code block sequence, wherein system bits corresponding to each code block in the first QC_LDPC code block sequence comprise information bits and check bits, and the information bits comprise first filling bits; removing the bit corresponding to a large column weight in each code block; removing the first filling bits in each code block; sequentially performing bit splicing on each code block, and selectively filling a second filling bit based on the length of the code block, so that each code block meets a preset data structure; and respectively storing each code block in a cyclic cache region, selecting and reading cache bits, completing rate matching of the first QC_LDPC code block sequence, and obtaining a second QC_LDPC code block sequence. By using the method, the data processing rate and throughput of the communication system can be remarkably improved.

Description

technical field [0001] The present disclosure relates to a data processing method and a communication device, and in particular to a data processing method, a communication device, a network device and a storage medium based on a QC_LDPC code (Quasi-CyslicLow Density Parity Check Code, quasi-cyclic low density parity check code). Background technique [0002] In the field of mobile communication, channel coding technology is very important. The essence of channel coding is to process the received bits (information bits) to obtain a series of new bits (check bits), and put the two together to obtain an encoded code block. At present, the commonly used channel coding systems are BCH code (an error correction code jointly proposed by R.C.Bose, D.K.Chaudhuri and A.Hocquenghem), RS code (ie Reed-Solomon error correction code), convolutional code, Turbo code (a concatenated code first proposed by Claude. Berrou et al. in 1993) and LDPC code (Low Density Parity Check Code, Low Den...
