Triple Hybrid Terresstrial FSO/RF/MMW System with Receiver's Diversity

The continuously expanding demand for faster and more efficient communication, dictates the research and development of more contemporary telecommunication systems, such as the FSO, characterized by their very high data rates and bandwidth. However, the optical beam, propagating through the atmosphere, suffers from phenomena with negative impact on the performance of the overall communication system. A commonly used technique to counterbalance these obstacles is to use a hybrid FSO/RF or FSO/MMW system. In this work, we further develop this idea, by studying a triple hybrid FSO/MMW/RF system, operating over turbulent atmospheric channel with pointing errors, along with Weibull and Rayleigh fading for the MMW and RF links, respectively. The mathematical expression for the outage performance estimation of the triple hybrid system is derived and its efficiency is verified through the numerical results.
