关于ρ度量的一个MacWilliams恒等式
A MacWilliams Identity Respecting to ρ Metric
摘要
Abstract
The definition of the exact complete p weight enumerator of a linear code over Mn×s (Zk) and a MacWilliams identity for the weight enumerator are given. The relation among the exact complete p weight enumerator of a linear code over Mn×s (Zk), the exact weight enumerator and the complete weight enumerator of a linear code over Zk is researched, which indicates that the exact complete p weight enumerator is more general than the other, and it may be better to explore the structure of code and to calculate decoding error probability.关键词
