OFDM-FSO Communication System Analysis

Abstract

In this paper, we have presented the performance analysis of a QAM-orthogonal frequency-division multiplexing (OFDM)-free space optics (FSO) (QAM-OFDM-FSO) transmission system, based on optical double sideband (ODSB), optical single sideband (OSSB), and optical vestigial sideband transmission scheme. Simulation models have been developed for optimizing the performance of the FSO system under different atmospheric conditions.
