Channel Modeling for IRS-Assisted FSO Systems
Hedieh Ajam, Marzieh Najafi, Vahid Jamali +1
In this paper, we develop an analytical channel model for intelligent reflecting surface (IRS)-assisted free space optical (FSO) systems. Unlike IRS-assisted radio frequency system…
Ergodic Sum Rate Analysis of UAV-Based Relay Networks with Mixed RF-FSO Channels
Hedieh Ajam, Marzieh Najafi, Vahid Jamali +1
Unmanned aerial vehicle (UAV)-based communications is a promising new technology that can add a wide range of new capabilities to the current network infrastructure. Given the flex…
Statistical Modeling of the FSO Fronthaul Channel for UAV-based Communications
Marzieh Najafi, Hedieh Ajam, Vahid Jamali +3
In this paper, we investigate the statistics of the free space optics (FSO) communication channel between a hovering unmanned aerial vehicle (UAV) and a central unit. Two unique ch…
Statistical Modeling of FSO Fronthaul Channel for Drone-based Networks
Marzieh Najafi, Hedieh Ajam, Vahid Jamali +3
We consider a drone-based communication network, where several drones hover above an area and serve as mobile remote radio heads for a large number of mobile users. We assume that…
