Abstract
Free space optical communication is a cost-efficient method for accessing high-bandwidth applications which has gained more attention with latest commercialization achievements. Fading induced by turbulence is a serious issue in FSO link which harshly deteriorates link performance. In order to reduce the turbulence effect caused by scintillation, various researches have been carried out in the domain of FSO network. This research work has employed one such technique in order to reduce the scintillation effect, which involves the use of homodyne detection in conjunction with the multibeam technique in WDM FSO system. Performance comparison of the single beam and multibeam WDM FSO system using homodyne detection in context of BER, Q factor and eye height have been explored for the scintillating effect in this paper.
