摘要
在时变滤波及信号合成应用中,对信号的自相关函数小波变换和从小波反变换后的自相关函数中提取信号的方法进行适当的改进,使信号的特征简便地得到重构.
In the applications of time variant filter and signal composition, properly improving the method of picking up signal from Wavelet transform of signal autocorrelation function and autocorrelation function of Wavelet inverse transform, characteristics of signal can be reconstructed easily.
