给出了环F2+uF2+vF2+uvF2上所有长度为2 S的(1+u+v)-常循环码的结构,并得到了每个常循环码的码字个数和对偶.在其他结果中,我们研究了这种自对偶常循环码的形式,并给出了这种码的个数。最后给出了所有长度为2、4和8的自对偶常循环码。
In this paper, we give the structures of all (1+ u+ v)-constacyclic codes of length 2 s over F 2+ u F 2+ v F 2+ u v F 2, we also obtain the number of codewords, and the dual of each constacyclic code. Among other results, we study the form of such constacyclic codes that are self-dual and give the number of these codes. We end by giving all self-dual constacyclic codes of length 2, 4 and 8.
