摘要:Non-binary low-density parity check (NB-LDPC) codes are an extension of binary LDPC codes withsignificantly better performance. Although various kinds of low-complexity iterative decoding algorithmshave been proposed, there is a big challenge for VLSI implementation of NBLDPC decoders due to its highcomplexity and long latency. In this brief, highly efficient check node processing scheme, which theprocessing delay greatly reduced, including Min-Max decoding algorithm and check node unit areproposed. Compare with previous works, less than 52% could be reduced for the latency of check nodeunit. In addition, the efficiency of the presented techniques is design to demonstrate for the (620, 310) NBQC-LDPCdecoder.
