循环码的盲识别方法

摘要

对信道编码中的循环码识别方法进行了研究。根据循环码的线性结构和生成多项式的根特征,建立了循环码的识别模型,在较高的误码率条件下,采用秩函数和码根特征的方法解决了循环码的盲识别问题。仿真结果分析表明,该方法能够对循环码进行有效的盲识别,具有较好的容错性能。%The blind recognition method of cyclic codes in channel coding is researched. The recognition model is established, and the rank function and the character of codes roots are used to solve the blind recognition of cyclic codes in condition of higher BER. Simulation experiments show that cyclic codes could be effectively recognized.
