【摘要】:針對本原BCH碼編碼參數(shù)的盲識別問題,該文提出了一種基于概率逼近的盲識別方法。首先,利用Gauss分布和Poisson分布逼近隨機碼字的根概率特性,確定了搜索BCH碼長的門限;然后,通過分析本原域元素的檢錯能力及同構(gòu)對域的影響,應(yīng)用臨近域?qū)Φ姆椒ù_定編碼域,提高了其識別能力;最后,給出識別生成多項式時的共軛根系表,從而減少了計算量。仿真結(jié)果表明,在較高的誤碼率下,該方法能快速地識別出BCH碼編碼所采用的編碼參數(shù)。
[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).
