Step-wise implementation of a downlink OFDM system with one Base Station and 2 UEs, Channel Estimation using Max Likelihood, Repetition Coding, and 16QAM modulation. The system uses 20 subcarriers, 5 ...
This repository provides MATLAB simulations for analyzing hostile wireless channels. You will explore important features such as Rayleigh fading, Doppler effects, and delay spread. The simulations ...
Abstract: The use of cyclic prefix (CP) allows all existing orthogonal frequency-division multiplexing or multiple access (OFDM/OFDMA) systems to realize high-data-rate transmission in ...
Abstract: Cyclic prefix (CP) is used in OFDM/OFDMA systems for data transmission over multipath channels at a dear price of spectral efficiency degradation. This work aims to design a CP-free ...
Orthogonal frequency division multiple access (OFDMA) is a version of OFDM (orthogonal frequency division multiplexing) modulation that happens to be optimized for multiple users, specifically for ...
