摘要
Constacyclic codes are an important class of linear codes in coding theory. Many optimal linear codes are directly derived from constacyclic codes. In this paper, (1 - uv)-constacyclic codes over the local ring are studied. It is proved that the image of a (1 - uv)-constacyclic code of length n over under a Gray map is a distance invariant quasi-cyclic code of index p (2) and length p (3) n over . Several examples of optimal linear codes over from (1 - uv)-constacyclic codes over are given.
