Channel Modeling for Mobile Airborne FSO Backhauling

2024 IEEE Wireless Communications and Networking Conference (WCNC)
With its high capacity and immunity to electromagnetic interference, free space optical (FSO) communication is positioned to be a key connectivity solution for airborne backhauling. In this paper, we consider a scenario where a fleet of high-altitude platform stations (HAPSs) follow a pre-defined circular trajectory and provide airborne backhauling to ...
