In this letter, we consider a recently introduced doubly inverted Gamma-Gamma (IGGG) turbulence channel model and analyze the performance of a multi-hop unmanned-aerial-vehicle (UAV)-based free space ...

This paper studies the performance of mixed millimeter-wave radio-frequency (mmWave RF), free-space optics (FSO) systems in a highly scalable and cost-effective solution for fifth-generation (5G) ...
