摘要
小波变换基于模极大值的去噪方法具有非线性及自适应特性,而且特别适合于进行非平稳的微弱信号及具有较多奇异点信号的消噪,这种信号特点恰好是心电信号最突出的特征,也是常规信号处理方法遇到的最大难题。本文简述了小波变换模极大值去噪方法在心电信号处理中的应用,并证实这种方法可以在信号消噪的同时有效地改善信噪比,并同时提高信号的分辨率。
Wavelet based signal processing and analysis is an developing and still growing field in the discipline of Biomedical Engineering Singularities often carry the most important information contained in biomedical signal So in this paper, we developed a method to eliminate the noise by wavelet transform modulus maxima It can both improve the signal noise ratio and increase resolutions of the electrocardic signals
