[КНИГА][B] Frames and bases: An introductory course

O Christensen - 2008 - books.google.com
During the last several years, frames have become increasingly popular; they have
appeared in a large number of applications, and several concrete constructions of frames of …

The mystery of Gabor frames

K Gröchenig - Journal of Fourier Analysis and Applications, 2014 - Springer
This is a survey about the theory of Gabor frames. We review the structural results about
Gabor frames over a lattice and then discuss the few known results about the fine structure …

Sub-Nyquist sampling of short pulses

E Matusiak, YC Eldar - IEEE Transactions on Signal Processing, 2011 - ieeexplore.ieee.org
We develop sub-Nyquist sampling systems for analog signals comprised of several, possibly
overlap**, finite duration pulses with unknown shapes and time positions. Efficient …

[HTML][HTML] Pairs of dual Gabor frame generators with compact support and desired frequency localization

O Christensen - Applied and Computational Harmonic Analysis, 2006 - Elsevier
Let g∈ L2 (R) be a compactly supported function, whose integer-translates [Formula: see
text] form a partition of unity. We prove that for certain translation and modulation …

Gabor frames on non-Archimedean fields

O Ahmad, FA Shah, NA Sheikh - International Journal of Geometric …, 2018 - World Scientific
In this paper, we introduce the concept of periodic Gabor frames on non-Archimedean fields
of positive characteristic. We first establish a necessary and sufficient condition for a periodic …

Dual Gabor frames: theory and computational aspects

T Werther, YC Eldar… - IEEE Transactions on …, 2005 - ieeexplore.ieee.org
We consider a general method for constructing dual Gabor elements different from the
canonical dual. Our approach is based on combining two Gabor frames such that the …

Finite discrete Gabor analysis

PL Søndergaard - 2007 - orbit.dtu.dk
Gabor analysis is a method for analyzing signals through the use of a set of basic building
blocks. The building blocks consists of a certain function (the window) that is shifted in time …

Energy propagation in deep convolutional neural networks

T Wiatowski, P Grohs, H Bölcskei - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
Many practical machine learning tasks employ very deep convolutional neural networks.
Such large depths pose formidable computational challenges in training and operating the …

[HTML][HTML] Zak transforms and Gabor frames of totally positive functions and exponential B-splines

T Kloos, J Stöckler - Journal of approximation theory, 2014 - Elsevier
We study totally positive (TP) functions of finite type and exponential B-splines as window
functions for Gabor frames. We establish the connection of the Zak transform of these two …

Gabor windows supported on [− 1, 1] and compactly supported dual windows

O Christensen, HO Kim, RY Kim - Applied and Computational Harmonic …, 2010 - Elsevier
Consider a bounded function g supported on [− 1, 1] and a modulation parameter b∈] 1/2, 1
[for which the Gabor system [Formula: see text] is a frame. We show that such a frame …
