Abstract [en] : Analogous to the density criterion for Gabor frames and Riesz bases in the space of square integrable functions, we develop a necessary density condition for time–frequency localized operators in the realm of operator identification. The developed framework can be seen as a generalization of both, the density result for Gabor frames and Riesz bases, and the identifiability theorem for so-called operator Paley–Wiener spaces.
