摘要: 现代数字通信中常常进行信道编码识别处理.目前RS(Reed-Solomon,RS)码盲识别需对高阶域下所有谱分量进行求取,计算较为复杂,因此提出了一种基于二元域等效的识别方法.首先根据有限域性质将RS码等效为二元域上的线性分组码,然后建立码长、信息分组长度、生成多项式和本原多项式的关联模型.通过遍历各阶本原多项式,并验证二元线性分组码的校验向量,完成各参数的联合识别.仿真结果和理论分析表明,该方法在提升抗误码性能的同时有效减少了计算量,可用于智能通信和通信侦察等系统中.

Abstract: Channel coding identification is often required in modern digital communications.As the existing blind identification methods for RS code are complicated for the reason that all spectral components in high-order domain need to be calculated,a method based on binary equivalence is proposed.Firstly,RS code is equivalent to binary linear block code according to finite field properties,with the establishment of the association model between code length,information block length,generator polynomial and primitive polynomial.Then,the various parameters of RS code are identified by traversing primitive polynomials and verifying parity check vectors of the binary linear block code.Simulation results and theoretical analysis show that the proposed method can improve error-resilient performance and reduce computation cost as well,which proves its availability in intelligent communication and communication reconnaissance systems.
