摘要
利用GHM多小波,采用通用的二变量阈值法,对多小波用于信号去噪中的阈值选取给出了具体的方法,对单小波与多小波的去噪方法进行了比较。通过实验结果可以看出,多小波在信号去噪的效果上明显优于单小波。
The method of choosing threshold while using multi- wavelet in signal de-noising is presented. It used GHM multiple wavelet and the bivariate universal threshold. A comparison is made between single wavelet and multiple wavelets in signal de - nosing. Experimental results show that multiple wavelets generally outperform single wavelet.
