Reconstruction of a compactly supported function from the discrete sampling of its Fourier transform
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 1999)
De Fourier a wavelets : un breve recorrido por el análisis tiempo-frecuencia
(2020)
Un pequeño tour por el análisis de Fourier. Definimos a la transformada continua de Fourier, presentamos y estudiamos los resultados principales de la serie de Fourier y de la transformada de Fourier discreta. Analizamos ...
A discrete Fourier transform associated with the affine Hecke algebra
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
We introduce an explicit representation of the double affine Hecke algebra (of type A(1)) at q = 1 that gives rise to a periodic counterpart of a well-known Fourier transform associated with the affine Hecke algebra. (C) ...
Approximating functions from sampled Fourier data using spline pseudofilters
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2008)
User Identification and Verification from a Pair of Simultaneous EEG Channels Using Transform Based Features
In this study, the approach of combined features from two simultaneous Electroencephalogram (EEG) channels when a user is performing a certain mental task is discussed to increase the discrimination degree among subject ...
Application of block matrix theory to obtain the inverse transform of the vector-valued DFT
(Hikari Ltd., 2015)
We study the vector-valued discrete Fourier transform (vector-valued DFT) and its inverse transform, the vector-valued DFT inversion, through its block matrix representation. These transforms are defined for N- periodic ...
A Parallel Framework with Block Matrices of a Discrete Fourier Transform for Vector-Valued Discrete-Time Signals
(Hindawi Publishing Corporation, 2015)
This paper presents a parallel implementation of a kind of discrete Fourier transform (DFT): the vector-valued DFT. The vector-valued DFT is a novel tool to analyze the spectra of vector-valued discrete-time signals. This ...
