小波变换在心电信号去噪中的应用

Application of Wavelet Transform for ECG Signal Denoising

本文以小波变换为基础,介绍了小波去噪的方法和步骤,并通过具体的实例分析,说明小波去噪的效果明显优于传统的滤波效果,软阈值去噪的效果明显的优于硬阈值去噪的效果。

Based on the wavelet transform,the ways and process of wavelet de-noising are presented in the paper.The detail experimental results show that wavelet de-noising is better than traditional filtering ways,and the soft-threshold denoising is obviously better than the hard- threshold de-noising.
