摘要:

环F2+uF2是介于环Z4与域F4之间的一种四元素环,因此它分享了环Z4和域F4的一些好的性质,此环上的编码理论研究已成为一个新的热点。本文给出了环F2+uF2上任意偶长度的循环码的结构定理,并给出任意长度的循环码的计数公式。

关键词: 环F2+uF2 循环码 离散傅里叶变换

Abstract:

Ring F2+uF2 is a four-element ring which shares some good properties of both Z4 and F4. The coding theory over this ring has recently become a new ho  t topic among coding theorists. In this paper, we give the structure of the cyclic codes over F2+uF2 for arbitrary even lengths, and determine the numb  ber of cyclic codes for a given length.

Key words: (ring F2+uF2, cyclic codes, DFT)
