摘　　要：Reed-Solomon (RS)码具有优良的纠随机错误和突发错误的能力,被广泛应用于通信系统中。依据RS码定义的计算映射与按BCH子码编码2种不同的编码方式,对RS码性能增强算法进行了分类总结,并对比了这2类性能增强算法的异同。仿真结果表明,相对于传统的BMA译码算法,在误帧率为10-3时,KV算法可以提升RS码0.35 d B的性能增益,Chase译码算法有大约0.65 d B的增益,指出了RS码性能增强算法中Chase列表译码算法的后续研究方向。The Reed-Solomon(RS)code has excellent capability in correcting random and paroxysmal errors,and it is widely applied to communication systems.In this paper,based on such two kinds of encoding methods as computational mapping and BCH coding,the RS code performance enhancement algorithm is classified and summarized,and the similarities and differences of the two kinds of performance enhancement algorithm are compared.The simulation results show that,compared with the traditional BMA decoding algorithm,when the fame error rate is 10-3,KV algorithm can promote the performance gain by about 0.35 dB over BMA algorithm,and the Chase decoding algorithm can achieve about 0.65 dB.Finally,the research direction of Chase decoding algorithm is pointed out.
