摘要

本文研究了Haar小波包库内各种正交基对应的正交变换用于对随机数字信号进行处理的问题，提出了一种小波包基的编码方案，并且从方差分布、均方误差、率失真函数的角度对各种Haar小波包基对应的正交变换在数据压缩、广义维纳滤波和变换编码中的性能进行比较，总结了其规律．

Abstract

In this paper

a kind of orthogonal transforms associated with orthogonal bases in libary ofHaar wavelet packets is studied to process random digital signals. A coding method for the bases in a libare of wavelet packets is proposed. The performance of these orthogonal transforms in data compression

generalized Wiener filtering and transform coding is compared using variance distribution

mean squared error and rate distortion function. In the end

the laws are summarized.
