Sometimes, especially in foggy weather, a hold-up of migrants occurs. This autumn, for instan...

In this letter, we investigate the ergodic capacity of unmanned aerial vehicle (UAV)-based free space optics (FSO) links over random foggy channel. More specifically, derive composite probability density function (PDF) and close approximation for moments PDF using statistical model a UAV-based 3D pointing error With it, obtain upper bound asymptotic two possible detection techniques intensity m...
