BCH(31,21)码的解码及其软件实现

The Decipher and Software Realization of BCH(31,21)Code

从实用的角度论述了BCH(31,21)码的解码原理。利用计算出的伴随式s1和s3判定BCH(31,21)码的错误并纠正。从编程角度提出了便于计算伴随式的方法,最后给出了用C51实现该解码的程序代码。

This article practicably introduce s the decipher theory of BCH(31,21)code.Through us-ing the concomitant formula s1and s3which calculated,finds the BCH(31,21)mistranslation then cor-rects;from the view of program,adva nces the method which conveniently c alculate the concomitant formu-la.Finally,gives the decipher prog ram by C51language.
