Application of the AAK theory for sparse approximation of exponential sums
Gerlind Plonka, Vlada Pototskaia
In this paper, we derive a new method for optimal - and -approximation of discrete signals on whose entries can be represented as an exponential…

Enforcing uniqueness in one-dimensional phase retrieval by additional signal information in time domain
Robert Beinert, Gerlind Plonka
Considering the ambiguousness of the discrete-time phase retrieval problem to recover a signal from its Fourier intensities, one can ask the question: what additional information a…

A sparse Fast Fourier Algorithm for Real Nonnegative Vectors
Gerlind Plonka, Katrin Wannenwetsch
In this paper we propose a new fast Fourier transform to recover a real nonnegative signal from its discrete Fourier transform. If the signal appears to hav…
