On the time-frequency representation of operators and generalized Gabor multiplier approximations
The problem of representation and approximation of linear operators by means of modification in the time-frequency domain is considered. Before turning to the discrete and sub-sampled case, a complete characterization of linear operators by means of a twisted convolution in the continuous time-frequency domain is suggested. Subsequently, existing results on approximation by time-frequency multi...
متن کاملOn the Krein-Langer integral representation of generalized Nevanlinna functions
The Krĕın-Langer integral representation of a matrix-valued generalized Nevanlinna function arises in problems of spectral theory and interpolation. A version of this formula which is suitable for such problems, and a corresponding Stieltjes inversion formula, are derived. Some classes of generalized Nevanlinna functions which are defined in terms of behavior at infinity are characterized in te...
متن کاملRepresentation of Operators in the Time-frequency Domain and Generalized Gabor Multipliers
Abstract. Starting from a general operator representation in the time-frequency domain, this paper addresses the problem of approximating linear operators by operators that are diagonal or band-diagonal with respect to Gabor frames. A characterization of operators that can be realized as Gabor multipliers is given and necessary conditions for the existence of (Hilbert-Schmidt) optimal Gabor mul...
متن کاملAmplitudes of mono-components and representation by generalized sampling functions
A mono-component is a real-valued signal of finite energy that has non-negative instantaneous frequencies, which may be defined as the derivative of the phase function of the given real-valued signal through the approach of canonical amplitude-phase modulation. We study in this article how the amplitude is determined by its phase in a canonical amplitude-phase modulation. Our finding is that su...
متن کاملRepresentation of linear operators by Gabor multipliers
We consider a continuous version of Gabor multipliers: operators consisting of a short-time Fourier transform, followed by multiplication by a distribution on phase space (called the Gabor symbol), followed by an inverse short-time Fourier transform, allowing different localizing windows for the forward and inverse transforms. For a given pair of forward and inverse windows, which linear operat...
