| 摘 要： | 文章根据coiflet小波在各个尺度上的不同的带通滤波特性，并利用小波变换多分辨的特点对心电信号进行滤波。文中通过软、硬阈值折衷函数及自适应阈值策略对MIT／BIH国际标准数据库中的ECG信号进行了处理与验证。实验结果表明，该算法能较好的抑制心电信号中的各类噪声干扰。

| Abstract: | This article applies the multi-resolution anylysis(MRA) of wavelet transform(WT) to suppress the different types of noises exisiting in ECG signals,based on the characteristics that coiflet is a set of band-pass filters having different freqrency bands in every scale.The algorithm is tested using MIT/BIH arrhythmia database with compromise between soft and hard thresholding operations and adaptive threshold value.The experiment results show that the different kinds of noise interference can be effectively r... |
