摘要
文章确立了环F2+uF2+…+ukF2上码长为奇数n的(1+uk)-循环码的结构,给出自对偶码存在的充要条件,讨论了环F2+uF2+…+ukF2上的(1+uk)-循环码及其对偶码的Gray映射,并且得到它们之间的关系。
The structure of (l+uk )-cyclic codes of odd length n over the ring F2 +uF2 +… +ukF2 is es- tablished. And the necessary conditions for the existence of self-dual codes are given. Finally, the Gray images of (l+uk)-cyclic codes and its dual codes are studied respectively, and their relationship is given.
