2010/1/8
A class of noncanonical duals for multiwindow Gabor (MWG) schemes, encompassing both rational and integer oversampling of the Gaborian combined time-frequency space, is considered. Using properties of...
The discrete (finite) Gabor scheme is generalized by incorporating multiwindows. Two approaches are presented for the analysis of the multiwindow scheme: the signal domain
approach and the Zak transf...

Abstract-The properties of the discrete Gabor scheme are considered
in the context of oversampling. The approach is based on the concept
of frames and utilizes the piecewise finite Zak transform (PF...
