On non-detectability of non-computability and the degree of non-computability of solutions of circuit and wave equations on digital computers
Holger Boche, Volker Pohl
It is known that there exist mathematical problems of practical relevance which cannot be computed on a Turing machine. An important example is the calculation of the first derivat…
Compressive phase retrieval of sparse bandlimited signals
Çağkan Yapar, Volker Pohl, Holger Boche
This contribution proposes a two stage strategy to allow for phase retrieval in state of the art sub-Nyquist sampling schemes for sparse multiband signals. The proposed strategy is…
Fast Compressive Phase Retrieval from Fourier Measurements
Çağkan Yapar, Volker Pohl, Holger Boche
This paper considers the problem of recovering a -sparse, -dimensional complex signal from Fourier magnitude measurements. It proposes a Fourier optics setup such that signal…
System Approximations and Generalized Measurements in Modern Sampling Theory
Holger Boche, Volker Pohl
This paper studies several aspects of signal reconstruction of sampled data in spaces of bandlimited functions. In the first part, signal spaces are characterized in which the clas…
Phase retrieval from low-rate samples
Volker Pohl, Fanny Yang, Holger Boche
The paper considers the phase retrieval problem in N-dimensional complex vector spaces. It provides two sets of deterministic measurement vectors which guarantee signal recovery fo…
Phaseless Signal Recovery in Infinite Dimensional Spaces using Structured Modulations
Volker Pohl, Fanny Yang, Holger Boche
This paper considers the recovery of continuous signals in infinite dimensional spaces from the magnitude of their frequency samples. It proposes a sampling scheme which involves a…
