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 ...

Efficient implementation of the Radon Transform using the Fast Fourier Transform (FFT) and the Fourier Slice Theorem in Python, with a Tkinter-based GUI for interactive usage. The Radon Transform is ...

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!
