Abstract : A class of non-canonical duals for the multiwindow Ga- bor scheme, incorporating both rational and integer over- sampling of the Gaborian combined time-frequency space, is considered. Using properties of Gabor frame matrices, block Discrete Fourier transforms, and results from num- ber theory, we establish existence conditions for the non- canonical duals for both integer and rational oversampling rates, in the signal domain. For comparison and complete- ness of the results, we also obtain the equivalent results in the Zak transform domain. We show that, using this ap- proach, both computational efficiency and stability of the Gabor scheme can be enhanced.
