变长信道编码系统的差错控制能力分析

On Error-Control Capability of Length-Varing Coding Systems

基于分组码周期结构的变长信道编码方法是文献［１］提出的一种新的编码方法，它能在节约大量的信道容量的同时还保持了原来系统的统计差错控制能力．本文继续从解析角度去深入分析这种变长信道编码系统的纠错能力和检错能力，井给出了一些有指导意义的结果．

A new length-varying coding system based on the periodic structure of block codeshas been proposed in[1].It has been proved that the new length-varying coding system has al-most the same error-control capability as that of the original constant length coding system.This paper goes on to investigate the error-correcting and error-detecting capability of the newlength-varying system. New results are presented.
