摘要: 信道编码码序列的信息侦获是当前研究的热点、难点领域,而识别信道编码参数是进行信息侦获的必要前提。提出了利用矩阵化简秩(RANK)特性识别RS码的码长和码根分布[T]进行RS码的生成多项式的识别方法,避免繁琐的矩阵化简获得生成矩阵,简单地解决了对RS码的盲参数识别。仿真实验表明该方法在较高的误码率条件下,可以达到较好的参数识别效果。

Abstract: The information recd of channel coding codes sequence is a hot and difficult field in current research,and the necessary precondition of information recd is the recognition of channel coding parameters.The rank characteristic of simplification of matrices is used to recognize the length of RS codes and the distribution of codes roots is used to recognize the creating polynomial of RS codes,avoiding the fussy simplification of matrices,the blind recognition of RS codes parameters are solved simply.Though high BER,simulation experiment shows the better performance of the parameter recognition.

Key words: channel coding, blind recognition, Reed-Solomon(RS) codes, rank characteristic, codes roots
