用MCS-51汇编实现BCH码的编码与译码

Coding and Decoding of BCH Code with MCS-51 Assembler

探讨在数据通信中用软件算法进行编码、解码和差错控制,以代替硬件功能。BCH码是通信中较为成熟的一种编码,文中详细介绍了用编程实现BCH[15,7]的编码、纠错与译码的原理,并给出了在51系列单片机上的算法流程与汇编语言源程序。在纠错译码方面采用了捕错译码法,收到了较好的效果。

The paper discusses arithmetic of BCH coding and decoding with MCS-51 assembly. It＇ s purpose is to replace the function of hardware by software. BCH is a better code used in communication. The paper expatiates on the principle of program for coding, decoding and error-correcting with BCH[ 15,7 ]. The flow chart and sound code with MCS-51 are presented. There is better effect in capture-error decode.
