Abstract

A new method for restrain the cross-terms of time-frequency distributions is presented. By introducing a phase-adjust function(PAF)based on the WVD, this method can restrain the cross-terms induced by the nonlinear character of the signal. And for multi-component signal, the CLEAN technique is adopted to filter out each component by a band-pass filter, and the cross-terms between the components are restrained. At the same time, this method has a high time-frequency convergency, the simulated results demonstrate the validity of it.
