Discrete multiwindow Gabor-type transforms
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 transform domain approach. Issues related to undersampling, critical sampling, and oversampling are considered. The analysis is based on the concept of frames and on generalized (Moore-Penrose) inverses. ...
متن کاملMultiwindow Gabor-type Representations and Signal Representation by Partial Information
Harmonic analysis has been the longest lasting and most powerful tool for dealing with signals and systems which involve both periodic and transient phenomena. Further impact on signal processing was facilitated by what we refer to as representations in combined spaces. These representations, motivated by Gabor’s concept of time-frequency information, cells have evolved in recent years into a r...
متن کاملMacromolecular sequence analysis using multiwindow Gabor representations
Multiwindow Gabor representations highlight fingerprints suitable for indexing of macromolecules, based on their local periodic structures. This paper presents a technique for analysis, and comparison of DNA and protein sequences. We use local periodicities to compare sequences and develop techniques that can compare the similarity between sequences in the combined space. We further show that u...
متن کاملOversampling of the Generalized Multiwindow Gabor Scheme
A class of non-canonical duals for the multiwindow Gabor scheme, incorporating both rational and integer oversampling of the Gaborian combined time-frequency space, is considered. Using properties of Gabor frame matrices, block Discrete Fourier transforms, and results from number theory, we establish existence conditions for the noncanonical duals for both integer and rational oversampling rate...
