RS码编码参数的盲识别
Blind Parameter Recognition of RS Codes
摘要
Abstract
As the existing methods for Reed-Solomon (RS) codes recognition are very complicated,a new method is proposed.Firstly,code weight distribution under different block length is counted.By defining similarity coefficient to the theoretical code weight,the most similar one is found,which corresponds to the correct code length.Then binary hypothesis test is established with a decision threshold to find code roots.By traversing all the primitive polynomials in the field,the complete distribution of continuous code roots is found,with which generator polynomial is calculated.Simulation results show that the computation cost of this method is significantly less than that of other methods,and it can effectively complete the recognition of code length and generator polynomial which has a recognition probability of 90％ for the commonly used RS codes when the bit error rate is less than 10-3.关键词
