The metaplectic action on modulation spaces

Hartmut Führ, Irina Shafkulovska

We study the mapping properties of metaplectic operators $S \in Mp (2 d, R)$ on modulation spaces of the type $M_{m}^{p, q} (R^{d})$ . Our main r…

Comparisons between Fourier and STFT multipliers: the smoothing effect of the Short-time Fourier Transform

Peter Balazs, Federico Bastianoni, Elena Cordero +2

We study the connection between STFT multipliers $A_{1 \otimes m}^{g_{1}, g_{2}}$ having windows $g_{1}, g_{2}$ , symbols $a (x, ω) = (1 \otimes m) (x, ω) = m (ω)$ , $(x, ω) \in R^{2 d}$ , and the Fo…

Numerical simulation of sound propagation in and around ducts using thin boundary elements

Wolfgang Kreuzer

Investigating the sound field in and around ducts is an important topic in acoustics, e.g. when simulating musical instruments or the human vocal tract. In this paper a method that…

Fusion of Probability Density Functions

Günther Koliander, Yousef El-Laham, Petar M. Djurić +1

Fusing probabilistic information is a fundamental task in signal and data processing with relevance to many fields of technology and science. In this work, we investigate the fusio…

Frame-related Sequences in Chains and Scales of Hilbert Spaces

Peter Balazs, Giorgia Bellomonte, Hessam Hosseinnezhad

Frames for Hilbert spaces are interesting for mathematicians but also important for applications e.g. in signal analysis and in physics. Both in mathematics and physics it is natur…

Fast Matching Pursuit with Multi-Gabor Dictionaries

Zdeněk Průša, Nicki Holighaus, Peter Balazs

Finding the best K-sparse approximation of a signal in a redundant dictionary is an NP-hard problem. Suboptimal greedy matching pursuit (MP) algorithms are generally used for this…
