环F2+vF2上线性码的t-Lee重量计数器的研究

摘要

基于环F2+vF2的四元有限环,在Lee重量的基础上,定义了t-Lee重量计数器,给出了环上互为对偶的线性码关于这个新计数器所满足的MacWilliams恒等式.%Based on ring F2 + vF2 with four elements, a t-Lee weight enumerator is given through Lee weight. A Mac Williams identity for the t-Lee weight enumerator of linear spaces of the ring F2+vF2 is proved.
