MATLAB Implementation of OFDM Simulation with Rayleigh Multipath Channels

This document presents a MATLAB-based OFDM simulation program that incorporates Rayleigh multipath channel modeling. The simulation utilizes 4 subcarriers to demonstrate fundamental OFDM principles. The implementation includes essential components such as QAM modulation for data mapping, IFFT/FFT operations for orthogonal subcarrier generation, cyclic prefix insertion for mitigating intersymbol interference, and channel equalization techniques to combat multipath effects. The program provides valuable insights into OFDM system performance analysis, enabling researchers to study the impact of multipath channels on signal transmission quality. Through detailed analysis of simulation results, users can draw conclusions about OFDM modulation and demodulation techniques, facilitating the design of more reliable and efficient communication systems. The code structure allows for easy parameter modification, including subcarrier count adjustment and channel model variations for extended research applications.
