Reed-So lomon (RS)码是目前最有效、应用最广的差错控制编码之一,是一类具有很强纠错能力的多进制BCH 码,它既可以纠正突发误, 也可以纠正随机错误。视、磁记录系统等方面。本文用matlab详细仿真实现RS编译码-Reed-So lomon (RS) code is the most effective, the most widely used one of error-controlling codes, is a kind of strong ability of the error correction into BCH code, it can correct mistakes sudden, also can correct random errors. RS code is mainly used in real-time higher mobile communications system, the deep space communications, digital satellite television, magnetic recording system, etc. In this paper, using matlab detailed simulation (RS decoder
