摘要: 本文給出(n,6,m)(m6)等重等距碼的一種構(gòu)造方法,側(cè)重討論了(n,6,m)等重等距碼的基本結(jié)構(gòu)形式,設(shè)計(jì)了幾類可以用來(lái)構(gòu)造(n,6,m)等重等距碼的基本單元子塊,并分析了構(gòu)造原則和實(shí)現(xiàn)結(jié)果,以及置換個(gè)數(shù)和性能分析。

Abstract: In this paper, a constituting method of binary codes of constant weight and distance with parameters (n, 6, m)(m 6) is given. The basic structure form of this kind of codes is discussed and the subset block of basic unit which can be used to constitute this kind of codes is designed. The constituting rule and realization result are analysed. Finally, the numbers of permutations and the properties of error-detecting codes are discussed. -
