OFDM Receiver Simulation Using MATLAB

When simulating OFDM receivers with MATLAB, you can obtain constellation diagrams and spectral plots of OFDM signals, which are valuable for analyzing signal performance and optimizing receiver parameters. The implementation typically involves using MATLAB's Communications Toolbox functions such as ofdmmod/ofdmdemod for modulation/demodulation, fft/ifft for orthogonal frequency division multiplexing, and scatterplot/psd for visualization. You can experiment with various OFDM parameters like the number of subcarriers or guard interval length to better understand receiver behavior and optimize parameters for improved performance. The simulation process may include adding channel impairments using awgn or rayleighchan functions to test receiver robustness. Ultimately, MATLAB provides a powerful platform for OFDM receiver simulation, facilitating deeper understanding of signal characteristics and receiver performance through customizable code implementations.
