基于小波和小波包的信号消噪方法分析

在实际的工程应用中,采集的数据信号存在着大量的电子线路热噪声、环境噪声等系统噪声,小波及小波包对除去噪声信号是非常有效的。采用多种方法对平稳、非平稳信号进行消噪处理,在Matlab环境下比较分析结果,从而找到检测信号的最佳手段。

Analysis on the Signal De-noising Based on Wavelet and Wavelet Packets

In actual construction,there are lots of thermal and environmental noises and of electronic circuit in the collected data signals and wavelet and wavelet packets are very effective in removing signal noises.Many methods are tested in the de-noising of stable and unstable signals to get the best ways to test signals after analyzing the results in the Matlab environment.
