Abstract
As is well known, the bilinear time-frequency distributions possesses a highly oscillatory cross term for each pair of signal terms. In this work, a novel method to suppress the cross-terms using beamforming is proposed. With Wigner-Ville Distribution as an example, the simulation results verify the feasibility of this method.
