摘要 有限交换环上常循环码在代数编码理论研究中占有重要的地位,特别是在构造有限域上高纠错性能非线性码中有着重要的应用.本文介绍了有限交换环上常循环码的研究进展,阐述了研究有限交换环上常循环码结构的一般方法及相关问题,分析了如何利用等距Gray映射构造有限域上的线性码. Constacyclic codes over finite commutative rings play a significant role in algebraic coding theory, especially have important applications for constructing nonlinear codes over finite fields with high error-correcting performance. In this paper, we introduce recent progress of constacyclic codes over finite commutative rings, set forth general methods of studying constacyclic codes over finite commutative rings and related problems, and analyze how to construct linear codes over finite fields by using isometric Gray maps.
