摘　　要：RS码(Reed-Solomon码)是一类具有很强纠错能力的多进制BCH码,广泛应用于通信和数据存储系统以便进行差错控制。鉴于RS码的广泛使用,其盲识别算法的研究也具有实际意义,可以帮助人们在信息截获、信息对抗和智能通信等领域取得重要突破。目前关于RS码编译码算法的研究已经有相当长的一段时间,其相关的理论算法已相对成熟,这里重点介绍RS码在实际中的具体应用及RS码编码算法和BM(Berlekamp-Massey)译码算法。在软件仿真实现方面,尽管MATLAB软件自带RS码编译码相关函数,还是要通过自编函数仿真实现RS码编译码器,以便于查看中间运算结果。RS（Reed-Solomon） code, as a kind of multinary BCH code with strong ability in error correction, is widely used in communication and data storage system so as to get the error controlled. For its wide use, the research on blind recognition algorithm of RS code is of great practical importance, and it could help the reseachers make significant breakthroughs in areas including information interception, network confrontation and intelligent communication. With a longtime research on RS coding/decoding algorithm, the relevant theoretic algorithm is now fairly mature. This paper presents the specific application of RS code and descrribes RS coding algorithm and BM （Berlekamp-Massey）decoding algorithm. Meanwhile, although the MATLAD software itself possesses RS coding/decoding functions, the simulation implementation of RS coder/decoder is realized with self-programed coding/decoding functions, and this would be convenient for observing the data during the funtions operation.
