A New Signal Denoising Algorithm from Wavelet Modulus Maxima
Yi Liu, Cheng Xu · 2007
In this paper, a new signal denoising algorithm from wavelet transform modulus maxima (WTMM) is proposed. It essentially combines Mallat's multiresolution analysis(MRA) theory and Donoho's denoising approach. With WTMM, we can improve the signal reconstruction approach and then an automatic denoising algorithm is possible. This method is of explicit physical meaning and can be implemented conveniently. Improved signal denoising results are obtained in comparison with the other denoising methods.
