Abstract: Let R=F2+uF2+u2F2 and R1=F2+uF2,the Gray map Ф from Rn to F3n2 and the map f from Rn1 to Rn are defined.By using the generator matrix of linear codes C over R,the generator matrices of the dual codes C⊥ and the Gray images Ф(C) of the linear codes C are given,and the linear codesФ(C⊥) are the dual codes of Ф(C) over F2.By the map f,linear codes over R1 are correspond to a class of linear codes over R.
摘要: 记R=F2+uF2+u2F2,R1=F2+uF2,定义了从Rn到F3n2的Gray映射Ф以及从Rn1到Rn的映射f。通过对环R上线性码C的生成矩阵的研究,给出了线性码C的对偶码C⊥和Gray像Ф(C)的生成矩阵,并且Ф(C)与Ф(C⊥)是F2上的对偶码。通过映射f将环R1上的线性码与环R上的一类线性码对应起来。
