二元k—重量码的检错性能
About Error-detecting Abilities of Binary Linear k-weight Codes C(n,k)
【摘要】 二元k-重量码C(n,k)定义为由所有重量分别为0,2,…,2k-2的n维向量组成的二元码,其中1<k≤[n/2]十1.本文通过对C(n,k)的对偶距离分布研究,讨论了C(n,k)的检错性能,给出了C(n,k)成为最住检错码的充要条件,并且研究了其渐近性质.
【Abstract】 Binary linear k-weight codes C(n, k) is defined as n-dimension vectors, the weight is 0, 2, … , 2k-2 respectively, and 1 <k ≤ [n/2] + 1. This paper has a detailed discussion about error-detecting abilities of C(n, k) by studying antithetic distance distribution of C(n, k), provide the sufficient and necessary conditions of C(n, k) to be the best error-detecting codes, and give a research about its approaching characteristics.
