再论二元非线性等重码的检错性能

On Error Detecting Capability for Binary Nonlinear Constant Weight Codes

本文利用对偶距离分布的性质，从理论上证明了文［４］的必要条件在δ＝１时实际上是充要条件，并得出对于（ｎ，２，ｗ）码，最佳检错码与检错好码是等价的；最后，本文讨论了（ｎ，２，ｗ）码不可检错误概率的界．

By using the properties of dual distance distribution,the necessary condition ofis proved to be also sufficient for δ =1.Moreover,we have that for ( n,2,ω )code,being proper is equivalent to being good.Finally,bounds of undetected error probability for (n,2,ω) code are obtained.
