摘要: 针对通信系统中错误不可避免的现状,在矩阵分析法的基础上,提出反向纠错思想。利用穷举法,穷举条件规定范围内所有可能的分组码和分组交织模式,在纠错译码后再进行判定,得出正确的交织参数。对该方法在不同的误码率条件下进行仿真,得出能够正确识别的误码范围。

关键词: 二进制线性分组码, 分组交织, 误码率, 交织关系, 交织长度

Abstract: Status for inevitable errors, this paper puts forward reverse correction ideas and lists all possible combination of block codes and packet interleaving modes using enumeration methods. And the decoding is used for correcting the errors. The right parameters of interleaving come out. This paper simulates the method in different Bit Error Rate(BER) and reaches an appropriate range of bit error rate.

Key words: binary linear block codes, packet interleaving, Bit Error Rate(BER), interleaving relationship
