Abstract: This paper deals with discrete Fourier transform (DFT)-based modulation and demodulation techniques for affine frequency division multiplexing (AFDM), as opposed to using the discrete affine ...

Abstract: This study aims to explore the application of frequency sweep signal analysis based on discrete Fourier transform in complex environments, in order to improve the accuracy and reliability of ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...

This repository implements the discrete gyrator (a rotation in the phase space) on the 2D Hermite–Kravchuk (HK) basis via the SU(2) representation—using Wigner small‑d coefficients. It includes an n=2 ...

Thanks for your interest in our work, we will continue to optimize our code. If you have any other questions, please feel free to raise them in the issues, and I will try my best to address them!

Introduction: Early detection of diseases on bean leaves is essential for preventing declines in agricultural productivity and mitigating broader agricultural challenges. However, some bean leaf ...
