Abstract

This work is focused to carry out the investigation of fading resistant coherent detected OFDM-FSO system using a simulated test-bed employing OSSB- and ODSB-schemes under clear weather conditions. The data rate transmission is enhanced to 1Tbps range by employing the coherent detection scheme over a prolonged FSO link as compared to direct detection based OFDM-FSO system (Sharma [18]). Further, the simulated work is also demonstrated for OSSB- and ODSB-schemes to report the best scheme to be used in CO-OFDM-FSO systems to achieve acceptable BER at high data rate transmission (up to1Tbps).
