A novel design based on integration of OFDM and FSO system is reported in this work to prolong the FSO link at high transmission rate under clear weather conditions and evaluates the performance of such hybrid systems using ODSB, OSSB and OTSB schemes.Simulations indicate that the hybrid OFDM-FSO promises considerably improved free space link with acceptable SNR and BER compared to traditional FSO systems.
