Modified Gabor Wigner Transform for Crisp Time Frequency Representation
Abstract—Gabor Wigner transform (GWT) avoids the crossterms and gives high clarity in time frequency (t-f) domain.The transform is however unable to provide a clear picture insituations when auto and cross components of Wignertransform of the multi component signal overlap. This paperpresents a new simple hybrid approach that overcomes thelimitations of GWT in an efficient manner by making use offractional Fourier transform and image processing technique.Experimental results demonstrate superiority of proposedscheme.
