Method description:

The principle of EWT is to divide the Fourier spectrum of the signal into continuous intervals, then construct wavelet filter banks on each interval for filtering, and finally obtain a group of AM and FM components through signal reconstruction. This method can identify the position of the feature information in the Fourier spectrum of the signal by using the wavelet filter bank with tight support characteristics, and adaptively extract the different frequency components of the signal.
