摘要

本文主要研究了统一复Hadamard变换(UCHT)，其变换矩阵包含元素/spl plusmn/1和/spl plusmn/i。介绍了超高温等离子体的新特性。根据新发现的性质，通过计算一组数据的实部和虚部的实Walsh Hadamard变换(WHT)，将其乘以一组常数复数值，并将变换后的值乘以一些常数复数因子，可以方便地计算出UCHT。

An algorithm to compute unified complex Hadamard transform

This paper focuses on the study of unified complex Hadamard transforms (UCHT) whose transformation matrices contain elements /spl plusmn/1 and /spl plusmn/i. New properties of the UCHT are presented. From the newly discovered properties, the UCHT is conveniently calculated by computing real Walsh Hadamard transform (WHT) of real and imaginary parts of a set of data, which are multiplied by a set of constant complex values, and multiplying the transformed values by some constant complex factors.
