Design of 64 QAM Transceiver Model and its Performance Analysis for FSO Communication

In this paper we have proposed a transceiver model which utilizes 64 QAM type of modulation scheme for free space optical communication, the unique feature of our proposed model is that it transmits very low optical power into FSO channel utilizing 64 QAM modulation scheme. The model performance was observed for various data rates up to 120Gbps and for a LOS range of 1.2 Km. The model was implemented on Optiwave – Optisystem software over a Free Space Optical communication channel.
