We determine all signals giving equality for the discrete Hirschman uncertainty principle. We
single out the case where the entropies of the time signal and its Fourier transform are …

We propose the use of spectral analysis on certain noncommutative finite groups in digital
signal processing and, in particular, image processing. We pay significant attention to …

An entropy-based uncertainty principle for a locally compact abelian group Page 1 Journal of
Functional Analysis 215 (2004) 241–252 An entropy-based uncertainty principle for a locally …

We have previously developed an uncertainty measure that is suitable for finitely-supported
(N samples) discrete-time signals. A specific instance of our measure has been termed the" …

The notion of a weak multiresolution analysis is defined over an arbitrary field in terms of
cyclic modules for a certain affine group ring. In this setting the basic properties of weak …

The purpose of this article is to direct reader's attention to some re-cent developments
concerning three Uncertainty Principles: the classical Heisenberg-Weyl Uncertainty …

We describe our initial approach to MCM OFDM that uses entropy-based signal models to
provide a sparse, efficient set of codes. Specifically, we consider applying a set of sparse …
