Empirical plunge profiles of time-frequency localization operators
Simon Halvdansson
For time-frequency localization operators, related to the short-time Fourier transform, with symbol , we work out the exact large eigenvalue behavior for rotationally invar…
On a time-frequency blurring operator with applications in data augmentation
Simon Halvdansson
Inspired by the success of recent data augmentation methods for signals which act on time-frequency representations, we introduce an operator which convolves the short-time Fourier…
Measure-operator convolutions and applications to mixed-state Gabor multipliers
Hans G. Feichtinger, Simon Halvdansson, Franz Luef
For the Weyl-Heisenberg group, convolutions between functions and operators were defined by Werner as a part of a framework called quantum harmonic analysis. We show how recent res…
Five ways to recover the symbol of a non-binary localization operator
Simon Halvdansson
Five constructive methods for recovering the symbol of a time-frequency localization operator with non-binary symbol are presented, two based on earlier work and three novel method…
