Fractional Fourier Transform: Main Properties and Inequalities

open access: yesMathematics, 2023
The fractional Fourier transform is a natural generalization of the Fourier transform. In this work, we recall the definition of the fractional Fourier transform and its relation to the conventional Fourier transform.

The class of Clifford-Fourier transforms [PDF]

open access: yes, 2011
Recently, there has been an increasing interest in the study of hypercomplex signals and their Fourier transforms. This paper aims to study such integral transforms from general principles, using 4 different yet equivalent definitions of the classical ...

On Katugampola Fourier Transform

open access: yesJournal of Mathematics, 2019
The aim of this article is to introduce a new definition for the Fourier transform. This new definition will be considered as one of the generalizations of the usual (classical) Fourier transform.

Some Essential Relations for the Quaternion Quadratic-Phase Fourier Transform

open access: yesMathematics, 2023
Motivated by the fact that the quaternion Fourier transform is a powerful tool in quaternion signal analysis, here, we study the quaternion quadratic-phase Fourier transform, which is a generalized version of the quaternion Fourier transform.

Fourier and Inverse Fourier Transform Model for Delayed Self-interferometry System

open access: yesIEEE Photonics Journal, 2020
Understanding the effects of laser phase and frequency noise on laser interferometry is significant for evaluating the system performance. To precisely study the performance limit caused by laser frequency noise, here we propose and demonstrate a ...

Large-Scale Discrete Fourier Transform on TPUs

open access: yesIEEE Access, 2021
In this work, we present two parallel algorithms for the large-scale discrete Fourier transform (DFT) on Tensor Processing Unit (TPU) clusters. The two parallel algorithms are associated with two DFT formulations: one formulation, denoted as KDFT, is ...
