二元Walsh特征函数的性质和计算法

ON PROPERTY AND COMPUTATIONS OF A TWO-VARIABLE WALSH CHARACTERISTIC FUNCTIONS

一个二元Walsh特征函数是相同于概率密度函数的二重Walsh变换。利用同样方法,我们可以确定n元Walsh特征函数和矩。由Walsh特征函数通过二进导数运算子引进矩的概念。

A two-variable Walsh characteristic function is identical to the double-Walsh transform of the probability density function. In a similar manner, an n-variable Walsh characteristic function and moment can be defined. It is now possible to derive moments from Walsh characteristic function via a dyadic derivative operator.
