摘　　要：在各类数字通信系统以及计算机存储和运算系统经常利用差错控制编码降低误码率,提高通信质量,满足对数据传输通道可靠性的要求。RS码是一种性能优良的前向纠错码,具有同时纠正随机错误和突发错误的能力,它的构造特点决定了其非常适合于纠正突发性错误。文中在阐述RS系统码编译码原理的基础上,提出了RS(16,12)缩短码的编译码方法,利用MATLAB对R S(16,12)缩短码在高斯信道和瑞利信道条件下的纠错能力进行仿真,并分析其纠错性能。In various digital communication systems and computer storage and computing systems,the error control coding is often used to reduce bit or symbol error rate,and thus to improve communication quality and meet the reliability requirements of data transmission.RS code,as an excellent forward error correction code,has the capability to correct both random error and burst error,and its structured characteristics feature its suitability for correcting burst errors.Based on description of the system code＇s encoding and decoding principles,this paper proposes shortened code＇s encoding and decoding method.And with MATLAB the shortened code＇s error correction capability in the AWGN and Rayleigh fading channel conditions is simulated.
