Due to their numerous advantages, communications over multicarrier schemes constitute an
appealing approach for broadband wireless systems. Especially, the strong penetration of …

Signal analysis with classical Gabor frames leads to a fixed time–frequency resolution over
the whole time–frequency plane. To overcome the limitations imposed by this rigidity, we …

A noniterative method for the reconstruction of the short-time fourier transform (STFT) phase
from the magnitude is presented. The method is based on the direct relationship between …

The Linear Time Frequency Analysis Toolbox is a MATLAB/Octave toolbox for computational
time-frequency analysis. It is intended both as an educational and computational tool. The …

An efficient algorithm for real-time signal reconstruction from the magnitude of the short-time
Fourier transform (STFT) is introduced. The proposed approach combines the strengths of …

Soundfield imaging is a special analysis methodology aimed at capturing the directional
components of the acoustic field and map** them onto a domain called “ray space”, where …

A class of random non-stationary signals termed timbre× dynamics is introduced and
studied. These signals are obtained by non-linear transformations of stationary random …

Various emerging applications in future wireless networks require rethinking the access
techniques not only from the capacity perspective but also satisfying a wide variety of …

We provide the foundations of a Hilbert space theory for the short-time Fourier transform
(STFT) where the flat tori TN 2= R 2/(Z× NZ)=[0, 1]×[0, N] act as phase spaces. We work on …

Due to its good potential for digital signal processing, discrete Gabor analysis has interested
some mathematicians. This paper addresses Gabor systems on discrete periodic sets, which …
