Based on the idea of wavelet multiresolution analysis, a method to reduce the noise of chaotic signal is proposed. First, the wavelet analysis of a chaotic time series is carried out to get the letter.
The different characteristics of the signal on different scales, and then the two high-frequency wavelet denoising is done for each high-frequency detail signal. Finally, the two wavelet denoising signal is superimposed linearly.
