摘要:

研究了具有两个距离$d$和$d+1$的$q$ -元分组码.给出了这类码的几种构造,因为在线性情况下,所有的码都可以通过线性等距码的简单修改而得到。上界的最大基数,这样的代码推导。表的下限和上限的小$q$和$n$。

英文摘要:

The $q$-ary block codes with two distances $d$ and $d+1$ are considered. Several constructions of such codes are given, as in the linear case all codes can be obtained by a simple modification of linear equidistant codes. Upper bounds for the maximum cardinality of such codes is derived. Tables of lower and upper bounds for small $q$ and $n$ are presented.
