Linear Independence of Time-Frequency Shifts?

Published 7 Jan 2014 in math.FA | (1401.1353v1)

Abstract: We investigate finite sections of Gabor frames and study the asymptotic behavior of their lower Riesz bound. From a numerical point of view, these sets of time-frequency shifts are linearly dependent, whereas from a rigorous analytic point of view, they are conjectured to be linearly independent.
