本文给出用条件重量表示Boole函数Walsh谱的一个表达式和用Walsh谱表示Boole函数的一个表达式,它们能把用Hamming重量叙述的结果和用Walsh谱叙述的结果互相“翻译”,从而指出一些准则的内在联系,同时也为利用快速Walsh进行计算提供一个途径。
In this paper, an expression of Walsh spectrum of Boole function is expressed by conditional weight and an expression of Boole function by Walsh spectrum, which can “translate” the result described by Hamming weight and the result described by Walsh spectrum to indicate Some of the guidelines of the internal relations, but also for the use of fast Walsh to provide a way to calculate.
