Representation of operators by sampling in the time-frequency domain

Résumé

Gabor multipliers are well-suited for the approximation of certain time-variant systems. However, this class of systems is rather restricted. To overcome this restriction, multiple Gabor multipliers allowing for more than one synthesis windows are introduced. The influence of the choice of the various parameters involved on approximation quality is studied for both classical and multiple Gabor multipliers. Fairly simple error estimates are provided, and the study is supplemented by numerical simulations.
