A New Signal Denoising Method using Iterative Thresholding of the Spectral Intrinsic Decomposition
Abstract : This paper presents a new signal denoising method based on the classical three step procedure analysis-threshold- synthesis and the Spectral Intrinsic Decomposition (SID). This method consists of an iterative thresholding of the SID components. If the wavelets denoising approach depends on the choice of the wavelet form, the SID-denoising proposed in this paper is self adaptive. The SID-based removal method reduces noise and can retain useful discontinuities of the signal as e ectively as the wavelet techniques based on soft thresholding.
