【摘要】：针对本原BCH码编码参数的盲识别问题,该文提出了一种基于概率逼近的盲识别方法。首先,利用Gauss分布和Poisson分布逼近随机码字的根概率特性,确定了搜索BCH码长的门限;然后,通过分析本原域元素的检错能力及同构对域的影响,应用临近域对的方法确定编码域,提高了其识别能力;最后,给出识别生成多项式时的共轭根系表,从而减少了计算量。仿真结果表明,在较高的误码率下,该方法能快速地识别出BCH码编码所采用的编码参数。
[Abstract]:In order to solve the problem of blind recognition of coding parameters of primitive BCH codes, a blind recognition method based on probability approximation is proposed in this paper. Firstly, the threshold of searching BCH code length is determined by using Gauss distribution and Poisson distribution to approximate the root probability characteristic of random code word. Then, by analyzing the error detection ability of local domain elements and the influence of isomorphism on the domain, the coding domain is determined by using the method of adjacent domain pair, and its recognition ability is improved. Finally, the conjugated root system table when recognizing and generating multinomial is given, thus reducing the amount of computation. The simulation results show that the proposed method can quickly identify the coding parameters used in BCH code coding at high bit error rate (BER).
