OFDM Simulation in Three-Path Rayleigh Channel

This study focuses on OFDM system performance evaluation through Simulink simulations in a three-path Rayleigh fading channel environment. Three key aspects are investigated: (1) Pilot-assisted channel estimation with BPSK modulation, analyzing BER performance and MSE curves; (2) Cyclic prefix-based time synchronization assuming frequency synchronization; (3) Cyclic prefix-based frequency synchronization assuming time synchronization. The implementation includes performance curve generation for SNR vs. estimation error, BER, acquisition probability, and frequency synchronization error.
