一种基于冗余离散小波变换的信号消噪技术

A Signal Denoising Technique Based on Redundant Discrete Wavelet Transform

在 Donoho算法的基础上提出了一种基于冗余离散小波变换的硬门限消噪技术 ,它能很好地克服 Donoho算法所呈现的振荡效应 ,仿真结果表明该算法是行之有效的。

In this paper, the authors present a signal denoising technique by hardthreshold based on redundant discrete wavelet transform inspired by Donoho algorithm. This method can be used to reduce the oscillating effects induced by Donoho algorithm, and the experiment result also indicates that the method is effective.
