Identification of stochastic operators
Götz E. Pfander, Pavel Zheltov
Based on the here developed functional analytic machinery we extend the theory of operator sampling and identification to apply to operators with stochastic spreading functions. We…
A time-frequency density criterion for operator identification
Niklas Grip, Götz E. Pfander, Peter Rashkov
We establish a necessary density criterion for the identifiability of time-frequency structured classes of Hilbert-Schmidt operators. The density condition is based on the density…
Boundedness of multilinear pseudo-differential operators on modulation spaces
Shahla Molahajloo, Kasso A. Okoudjou, Götz E. Pfander
Boundedness results for multilinear pseudodifferential operators on products of modulation spaces are derived based on ordered integrability conditions on the short-time Fourier tr…
