The reduction of interference terms in the time-frequency plane

There are few techniques for the reduction of interference terms. The most important between them is the reallocation technique. Other methods are based on the decomposition in frames of the signals to be processed. These frames represent discrete variants of some corresponding linear time-frequency representations. The aim of this paper is to propose a new method for the Wigner-Ville time-frequency representation's interference term reduction. This method is based on the conjoint use of the Gabor and Wigner-Ville time-frequency representations of the same signal. Simulations prove the performances of the new method.
