Block-equivalent finite Gabor frames
Oleg Asipchuk, Laura De Carli, Luis Rodriguez
We study finite systems of vectors whose frame operator matrices are unitarily equivalent, via explicit and computationally efficient unitary transformations, to block-diagonal mat…

Frequency-dependent stability for Gabor frames
Laura De Carli, Luis Rodriguez, Pierluigi Vellucci
We prove new stability results for a class of regular Gabor frames subject to frequency-dependent timing jitter under various conditions on the window function .
