Abstract

A theoretic approach to the belief-propagation - based weighted bit-flipping (BP-based WBF) algorithm is proposed for decoding low-density parity-check codes. The decoding algorithm can be easily simplified to IMWBF, MWBF, WBF or BF decoding algorithms by setting different parameters; hence it could offer a high flexible performance/complexity trade-off for hybrid decoding.

基于bp的LDPC码WBF译码算法的理论研究

提出了一种基于信念传播的加权比特翻转(BP-based WBF)算法的理论方法，用于解码低密度奇偶校验码。通过设置不同的参数，可以方便地将译码算法简化为IMWBF、MWBF、WBF或BF译码算法;因此，它可以为混合解码提供高度灵活的性能/复杂性权衡。
