Efficient discrete Gabor transform with weighted linear combination of analysis windows

A novel discrete Gabor transform (DGT) with a weighted linear combination of analysis windows is presented, which can utilise the optimal weights to change the shape and width of the combined analysis window so as to improve the time–frequency resolution of the Gabor spectrum. The optimal weights ca...
