MATLAB Simulation Model for Rayleigh Fading Channel with OFDM Implementation

Below is the MATLAB simulation model program for a Rayleigh fading channel. This code implements cyclic convolution for OFDM systems, where we first define key channel parameters such as Doppler shift, delay spread, and number of multipath components. The simulation generates OFDM signals using IFFT operations and applies cyclic prefix insertion. The transmitted signal then passes through the Rayleigh fading channel model, which generates complex Gaussian random variables to simulate multipath fading effects. At the receiver side, the model performs signal demodulation through FFT operations, channel equalization using techniques like Zero-Forcing or MMSE, and error rate calculation to evaluate system performance. This simulation framework enables comprehensive analysis of how Rayleigh fading impacts OFDM system performance, facilitating BER performance evaluation and system optimization. The code structure includes modular functions for channel generation, signal processing, and result visualization.
