BER Performance of the Hybrid FSO/RF Attenuation System

In this paper, we derived BER performance for hybrid FSO/RF systems operating over atmospheric attenuation channels. Simulation results are demonstrated to confirm the analytical results. From the results, we conclude that BER is decreasing as the adverse weather and further distance. If the FSO system is used, fog hampers communication, on the contrary, RF systems are immune to fog. Rain is just contrary. Therefore, we should take advantage of the hybrid system to conquer the disadvantages of one of them operating only, enhance the availability of the system.
