摘要
研究了有限链环R上常循环码的等价性,根据等价性给出了R上一些常循环码及其对偶码的结构.确定了该环上长度为ps的所有常循环码及其对偶码的结构.
Let R be a finite chain ring, and the characteristic of the residue field R be a prime number p. The equivalence of constacyclic codes over finite chain ring R are studied,and the structure of some constacyclic codes and their duals are given. The structure of all constacyclic codes with length p^s and their duals over the ring R are determined
