基于小波变换的信号去噪研究

Research on Signal Denoising Based on Wavelet Transfromation

基于小波变换对信号去噪进行了深入地分析和研究,结合去噪原理讨论和比较了实际应用中对小波基及阈值规则的合理选取问题。实验结果表明,利用该去噪方法能实现对各种信号的去噪,且效果比较明显。

This paper deeply analyses and researches the method of signal denoising based on wavelet transform. Combining with the denoising principle,the rational selection issue concerning more suitable wavelet base and the best threshold rule in actual application is discussed and compared.Experiment results indicates that the use of this denoising method can achieve the denoising of signals of various kinds,with obvious effects obtained.
