关于修改的沃尔什-哈达玛(W-H)变换的特点及其推广

Property and Expanding about Modified W-H Transforms

本文首先引入桥函数的概念,然后讨论桥函数与修改的沃尔什-哈达玛变换之间的关系,从而说明修改的W-H变换构造的物理本质。在此基础上,引入了另一种修改的沃尔什-哈达玛变换方阵,并建立了相应的快速算法。

The Bridge function is first introduced in this paper. And then the relations between bridge functions and modified W-H transforms are discussed, from which the physical nature of modified W-H transform can be revealed. Finally, another modified W-H transform is presented and the corresponding fast algorithm is established.
