Title: An automatic time-frequency procedure for interference suppression by exploiting their geometrical features
Author: Saulig, N; Sucic, V; Boashash, B
Abstract: This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville distribution by the Pseudo Wigner-Ville distribution. The resulting time-frequency distribution outperforms in terms of representation quality the Wigner-Ville distribution, the Pseudo Wigner-Ville distribution with fixed smoothing windows, as well as the Modified B distribution.
Description: This paper presents an adaptive algorithm for the optimal masking of the WVD by the Pseudo WVD where the structure of the inner artifacts of the WVD determines the lag smoothing window duration of the PWVD. (Additional details can be found in the comprehensive book on Time-Frequency Signal Analysis and Processing (see http://www.elsevier.com/locate/isbn/0080443354). In addition, the most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated).This paper presents an adaptive algorithm for the optimal masking of the WVD by the Pseudo-WVD .
