摘要 本文介绍了LDPC硬判决算法的思想,并提出了一种实用的计算机摸拟步骤,同时着重分析了门限值的选择对于中短随机码LDPC码译码的误码率和迭代次数的影响。 In this paper, the basic idea of hard-decoding algorism for LDPC codes is introduced and a kind of practically used computer simulation process is described. Then it analyses the error-performance and iteration times of decoding algorism for middle-sized random LDPC codes when different thresholds are chosen.
