Description

technical field [0001] The invention relates to the field of channel coding, in particular to a coding method of globally coupled low-density parity-check codes. Background technique [0002] As one of the important methods to improve transmission reliability, channel coding has always been a research hotspot in the field of communication. LDPC codes are regarded as a milestone in the field of error-correcting codes due to their excellent error-correcting performance and easy-to-implement hardware features. Compared with the traditional structure, the globally coupled LDPC code proposed in recent years has better coupling characteristics, and can enhance the information transmission of check nodes and variable nodes in the iterative decoding process through its global coupling part, which is highly reliable in high-speed transmission scenarios. Sexual needs offer a solution. [0003] The construction of globally coupled low-density parity-check codes is a research hotspot ...
