摘要
正整数数v,k,λ为一个t-(v,k,λ)设计的参数,利用t-(v,k,λ)设计的性质构作了二元矩阵C和C,以它们为码矩阵,证明了码矩阵C和(C)是非线性最优二元等距等重码并给出了它们成为最优检错码的必要条件.
The positive integers v,k,λ are parameters of t-(v,k,λ)design.By the properties of t-(v,k,λ) design,the binary matrices C and C are constructed.The matrix C and C are said to be code matrices,the two matrices are proved to be the nonlinear optimal binary constant weight codes and the necessary conditions of optimal error-detecting codes are obtained.
