On the Use of Rényi Entropy for Optimal Window Size Computation in the Short-Time Fourier Transform

Sylvain Meignen, Marcelo Alejandro Colominas, Duong-Hung Pham

ICASSP 2020accepted

In this paper, we investigate the determination of an optimal window length associated with the computation of the short time Fourier transform of multicomponent signals. In recent years the Rényi entropy has been widely used for that purpose, but the understanding of the significance of the obtaine…

A Novel Thresholding Technique for the Denoising of Multicomponent Signals

Duong-Hung Pham, Sylvain Meignen

ICASSP 2018accepted

This paper addresses the issues of the denoising and retrieval of the components of multicomponent signals from their short-time Fourier transform (STFT). After having recalled the hard-thresholding technique, in the STFT context, we develop a new thresholding technique by exploiting some limitation…
