Abstract: Fast Fourier Transform (FFT) is an important technology in signal processing and digital analysis. As an optimized FFT algorithm, the Winograd FFT algorithm can reduce the number of ...

This paper introduces a new encryption method aimed at improving the cryptography process through the use of splitting radix Fourier Transform technique called Split-Radix Fast Fourier Transforms ...

The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain ...

Abstract: Since its introduction in 1965 by Cooley and Tukey, the Fast Fourier Transform (FFT) has revolutionized signal processing, converting time domain data into frequency domain data with ...
