Abstract: The Cooley-Tukey FFT algorithm decomposes a discrete Fourier transform (DFT) of size n = km into smaller DFT of size k and m. In this paper we present a theorem that decomposes a polynomial ...

Fast-Fourier Transform in 2D. Examination of Cooley-Tukey Algorithm for 2D FFT, image I/O for FFT, and a shared memory implementation of FFT on the GPU.

Fourier transform is a key method for analyzing signals in both time and frequency domains. The FFT is a computational algorithm that efficiently computes the discrete Fourier transform (DFT) and its ...

Abstract: Algorithms for Fast Fourier Transforms (FFT) have been cornerstones of scientific computing since the 1960s, when hallmark achievements such as Cooley ...

In order to realize the real-time processing and analysis of astronomical ultra-wide bandwidth signals, this study proposes a sub-band division algorithm based on RFSoC. The algorithm uses Kaiser ...
