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 ...

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 ...

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 ...

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 ...
