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.
