摘要

近年来

在小波变换域实现信号的滤波引起了人们的极大重视

一些滤波方法也相继被提出.利用软门限来对信号的噪声加以滤除

是其中的一种重要方法.由于它操作方便

抑制噪声的效果好

故一经提出便在信号去噪中得到了重要应用.本文给出了一种最佳的软门限去噪方法

它与原有方法相比较可以给出更好的滤波结果.

Abstract

In recent years

filtering in wavelet domain became an important research field.Also

some new methods were developed.Denoising based on the soft thresholding is the famous one of them.Simple and effective make it attractive in many applications of signal denoising.In this paper

the optimal soft threshoding is presented.Compared with the soft thretholding

the proposed approach can give better results in signal denoising.
