A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...
(1)-Developed an advanced image processing project leveraging the Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) to analyze and manipulate image data. (2)-Implemented frequency ...
This project demonstrates the transmission of two digital signals over a shared communication medium using modulation techniques. It explores signal generation, low-pass filtering, ...
Abstract: The discrete Fourier transform is a very powerful tool of digital signal processing used for spectral domain analysis of signals. The radix-2 fast Fourier transform (FFT) is the most popular ...
Abstract: The paper presents a low complexity channel estimator based on windowed discrete Fourier transform (DFT) and scalar Wiener filter for orthogonal frequency division multiplexing (OFDM) mobile ...
