摘要

当前LDPC码的构造方法都是偏重于提高码的性能、降低编码复杂度2个方面

没有考虑码组之间的汉明距离和汉明距离分布

从而漏检部分突发错误。给出了一种次优的考虑码组汉明距离分布的构造方法

和已有的方法相比

这种方法构造的LDPC码不仅可以检突发长度小于校验矩阵秩的突发错误

并且保持纠随机错误性能不变。

Abstract

The coding of LDPC codes is focused on several aspects: high error-correction

low coding complexity and so on.All the construction methods do not give much consideration on hamming-distance and its distribution because of computation complexity.A suboptimal scheme which is with emphasis on hamming-distance and its distribution was presented.The codes introduced from this scheme can detect all burst-errors within the length of check matrix’s rank and has no loss in performance of random-error-correction.
