Abstract

The qq-ary block codes with two distances dd and d+1d+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 qq and nn are presented.
