摘要:  研究了环F2+uF2上1-Lee重量码与2-Lee重量射影码的结构性质,分别给出了一种构造环F2+uF2上1-Lee重量码和2-Lee重量射影码的方法.通过F2+uF2到F2上的Gray映射,得到了两类参数分别为[2m+1-2,m,2m]与[2m-1,m,2m-2]的二元最优线性码(m为正整数),后者等价于二元一阶ReedMuller码RM(1,m-1).

Abstract: The structure and properties of one-Lee weight codes and two-Lee weight projective codes over the ring F2+uF2 were investigated. A construction method of oneLee weight codes and twoLee weight projective codes over the ring F2+uF2 was given. Under the Gray map from F2+uF2 to F2, two classes of binary optimal linear codes with parameters [2m+1-2,m,2m] and [2m-1, m, 2m-2] were obtained, the latter is equivalent to the binary firstorder ReedMuller codes RM(1,m-1).
