General One-dimensional Clifford Fourier Transform and Application to Probability Theory

Said Fahlaoui, Hakim Monaim

In this paper, we present the general one-dimensional Clifford Fourier Transform. We derive fundamental properties: Plancherel theorem, reconstruction and convolution formulas. Add…

Titchmarsh theorem associated with QFT

Hakim Monaim, Said Fahlaoui

In this paper, we prove both of the Titchmarsh theorems associated with Two-Sided Quaternionic Fourier Transform and we conclude about Short-Time Two-Sided Quaternionic Fourier Tra…

Uncertainty Principles For the continuous Gabor quaternion linear canonical transform

Mohammed El Kassimi, Said Fahlaoui

Gabor transform is one of the performed tools for time-frequency signal analysis. The principal aim of this paper is to generalize the Gabor Fourier transform to the quaternion lin…

The two-sided Gabor quaternion Fourier transform and some uncertainty principles

Mohammed El Kassimi, Said Fahlaoui

In this paper, we define a new transform called the Gabor quaternionic Fourier transform (GQFT), which generalizes the classical windowed Fourier transform to quaternion valued-sig…

Wigner-Ville distribution associated with the quaternion offset linear canonical transforms

Mohammed El Kassimi, Youssef El haoui, Said Fahlaoui

The Wigner-Ville distribution (WVD) and quaternion offset linear canonical transform (QOLCT) are a useful tools in signal analysis and image processing. The purpose of this paper i…

Helgason Gabor Fourier transform and uncertainty principles

Mohammed El Kassimi, Mustapha Boujeddaine, Said Fahlaoui

Windowing a Fourier transform is a useful tool, which gives us the similarity between the signal and time frequency signal, and it allows to get sense when/where ceratin frequencie…

A heat kernel version of Miyachi's Theorem for the Laguerre hypergroup

Mohammed El Kassimi, Said Fahlaoui

Let the Laguerre Hypergroup. In this paper, we are going to formulate and prove an analogue of Miyachi's uncertainty principle for the Lagu…
