摘要
本文分析了二进制(2m,2,m)非线性等重码的不可检错误概率,证明了当m≥5时,它不是最佳检错码,从而完全证明了作者提出的:当n≥9时,不存在最佳二进制非线性等重码的猜想.
The probability of undetected error of the(2m,2,m) binary nonlnear constant weight codes is analysed in this paper.We prove that these nonlinear constant weight codes are no good for error-detecting if M≥5,so that the conjecture fiven by the author in 1989 is correct.
