MULTI-WINDOW GABOR FRAMES IN AMALGAM SPACES
Wiener amalgam space Gabor frame Wiener’s Lemma
2015/12/10
We show that multi-window Gabor frames with windows in the Wiener algebra W(L∞, `1) are Banach frames for all Wiener amalgam spaces. As a by-product of our results we prove thecanonical dual of a Gabo...
Banach Gabor frames with Hermite functions: polyanalytic spaces from the Heisenberg group
Gabor frames Heisenberg group Hermite functions
2011/2/23
Gabor frames with Hermite functions are equivalent to sampling sequences in true Fock spaces of polyanalytic functions. In the L2-case, such an equivalence follows from the unitarity of the polyanalyt...
A High-Resolution Technique for Ultrasound Harmonic Imaging Using Sparse Representations in Gabor Frames
Gabor frames harmonic imaging sparse representations
2010/1/6
Over the last few decades there were dramatic
improvements in ultrasound imaging quality with the utilization
of harmonic frequencies induced by both tissue and echo-contrast
agents. The advantages...
