摘要
定义了环F2+uF2上线性码的李重量分布的概念;利用域F2上线性码和对偶码的重量分布的关系及其Gray映射,得到了环F2+uF2上线性码及其对偶码各种重量分布的MacWilliams恒等式.
Lee weight distribution of linear codes over F2+uF2 was defined. By the relationship of linear codes and their dual codes over F2 and the Gray map, the MacWilliams identities for different weight enumerators of the linear codes over F2+ uFz and their dual codes were given.
