Time frequency analysis of operators and operator identification
2011 (English)Conference paper, Presentation (Refereed)
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.
