Abstract
Free Space Optical (FSO) communication technology becomes a promising solution for the future optical broadband networks. This work is focused to carry out the investigation of the performance of Orthogonal Frequency Division Multiplexing (OFDM) FSO system using Optical Single Sideband (OSSB), Optical Double Sideband (ODSB) and Optical Vestigial Sideband (OVSB) modulation scheme by employing Spatial Diversity. A 10 Gbps data is transmitted using 4-QAM through free air space under clear, haze and fog weather conditions. Results indicate that by employing spatial diversity, OFDM-FSO link range prolongs to 292 km with acceptable Signal to Noise Ratio (SNR) under clear weather condition whereas under fog weather condition, the maximum distance is extended to 3.24 km and OFDM-FSO system that uses OVSB modulation scheme provides increased values of SNR and power received than ODSB and OSSB modulation scheme.
