Outage Performance of Hybrid FSO/RF-FSO Communication System with single threshold

Now-a-days, people need the demand for higher bandwidth and high speed data rates for wireless communications. This paper discusses a communication system that combines radio frequency (RF) technologies and free space optical (FSO) to provide high-speed wireless communication. The system uses FSO as the primary link and RF-FSO with amplified and forward relaying as the secondary link. The performance of system is evaluated using the Fischer Snedecor and Nakagami m/F distributions to calculate the outage probability under different atmospheric conditions. The outage probability is expressed mathematically and simulated using MATLAB. Moreover, the proposed system is contrasted with a dual hop RF-FSO system and single FSO system with the same system parameters. The simulation results indicate that OP performance is degraded as atmospheric turbulence conditions becomes severe. Furthermore, the proposed hybrid system's performance is significantly superior to that of the dual hop RF/FSO system as well as single FSO system
