Abstract

This paper analytically investigates bit error rate (BER) performance of Free Space Optical (FSO) system. The FSO which is rapidly gaining popularity for its cost effectiveness and efficient means of transferring high data rates as well as optical fiber, whose data rate is limited by the atmospheric turbulence and scintillation conditions are studied. Orthogonal Frequency Division Multiplexing (OFDM) based Free Space Optical (FSO) communication is a technique which combines two developed technologies to enhance the performance of wireless optical communication system. The FSO channel modeled under atmospheric turbulence of Gamma-Gamma Distribution using BPSK, QPSK and 8-PSK modulation techniques. The performance analysis shows that the system performance improves with different PSK modulations applied to the OFDM-FSO system, the obtained results are the comparative study of Bit Error Rate (BER) vs. Signal to Noise Ratio (SNR), can be useful designing, predicting and evaluating the FSO systems.
