摘要

摘要: 在编码理论中，线性码的(最小)距离是一个极其重要的参数，它决定了码的纠错能力。设R为任一有限交换链环， a为其最大理想的一个生成元， R*为R的乘法单位群。对于任意wR*，该文利用R上任意长度的(1+aw)-常循环码的生成结构，通过计算这类码的高阶挠码，得到了R上任意长度的(1+aw)-常循环码的汉明距离，并研究了这类常循环码的齐次距离。这给编译有限链环上此类常循环码提供了重要的理论依据。

Abstract: In coding theory, the (minimum) distance of a code is a very important invariant, which always determines the error-correcting capability of the code. Let R be an arbitrary commutative finite chain ring, a is a generator of the unique maximal ideal andR* is the multiplicative group of units of R. In this paper, for any wR*, by using the generator polynomials of (1+aw)-constacyclic codes of any length over R, higher torsion codes of such codes are calculated. The Hamming distance of all(1+aw)-constacyclic codes of any length overR is determined and the exact homogeneous distance of some such codes is obtained. The result provides a theoretical basis for encoding and decoding for such constacyclic codes.
