Regionally optimised time–frequency distributions using finite mixture models

A method is presented for the improvement of the resolution and clarity of bilinear time–frequency distributions generated from signals consisting of a number of approximately time–frequency disjoint components. The method involves the determination of the parameters of a finite mixture of Gaussians...
