定义了环F2+vF2上码字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gray映射,给出了该环上线性码与对偶码之间各种重量分布的MacWilliams恒等式。
Lee weight distribution of linear codes over F2 + vF2 was defined. By the relationship of linear codes and their dual codes over F2 and the gray map, the MacWilliams identities between the linear codes and their dual code were given.
