小波自适应滤波器在DCG去噪中的应用

设计一种新的小波自适应滤波器。首先对原始信号进行小波分解,然后去除含噪多的小波系数,将重构后的数据作为滤波器的原始输入信号,而将含噪多的小波系数作为滤波器的参考输入信号。实验结果表明,该算法信噪比较高,去噪效果较好。此外,该算法的运算量小,很适合动态心电信号这种大量数据的运算。

Application of Wavelet Adaptive Filter in DCG De-noising

A new adaptive filter based on wavelet transform is designed.First,the original signal is decomposed by wavelet transform and the wavelet coefficients with main noises are canceled.Second,the reconstruction signal is selected as the original input of the adaptive filter and the wavelet coefficients with main noises are selected as the reference input of the adaptive filter.The experimental results show that this method is of bigger SNR and satisfied de-noising result.Finally,less computation of the method i...
