| 摘 要： | 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。然后利用软硬阈值小波去噪算法对ECG信号进行消噪处理。结果表明，软阈值去噪的效果明显的优于硬阈值去噪。

| Abstract: | In this paper, based on the wavelet transform, the ways and process of wavelet de-noising are presented. The experiment results show that wavelet De-noising is better than traditional filtering ways. The hard-thresholding De-noising and the soft- thresholding De-noising are used to de-noise the ECG signal .The results are compared with the two ways, the experiment results show that the soft-thresholding De-noising is obviously better than the hard- thresholding De-noising. |
