摘　　要：里德-索罗门(RS)编码是一类具有很强纠错能力的多进制BCH编码,它不但可以纠正随机错误,也能纠正突发错误。首先介绍了伽罗华域加法器和乘法器的设计,然后详细地阐述了RS(63,45)编译码器各模块的设计原理。对编译码器各模块先用Matlab进行设计,验证设计的正确性,再对译码器模块进行纠错性能测试。时序仿真结果表明,该译码器能实现最大的纠错能力。设计的编译码器能运用到实际的无线通信系统中去。The RS code is a non-binary BCH code,and has strong capability of error-correcting.The RS code can correct not only random errors but also burst errors.The paper first introduces the design of Galois field adder and multiplier,then detailedly explains the design principle of RS（63,45） coder and decoder.The paper first makes use of Matlab to design these modules to validate the correction of coder and decoder,then tests the errorcorrecting ability of the decoder.The time simulated result indicates the decoder has the best error-correcting ability.The coder and decoder designed can be used in modern wireless communications systems.
