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…
Non-Orthogonal Multiple Access for FSO Backhauling
Marzieh Najafi, Vahid Jamali, Panagiotis D. Diamantoulakis +2
We consider a free space optical (FSO) backhauling system which consists of two base stations (BSs) and one central unit (CU). We propose to employ non-orthogonal multiple access (…
Power Allocation and Cooperative Diversity in Two-Way Non-Regenerative Cognitive Radio Networks
Saeed Vahidian, Maryam Najafi, Marzieh Najafi +1
In this paper, we investigate the performance of a dual-hop block fading cognitive radio network with underlay spectrum sharing over independent but not necessarily identically dis…
C-RAN with Hybrid RF/FSO Fronthaul Links: Joint Optimization of RF Time Allocation and Fronthaul Compression
Marzieh Najafi, Vahid Jamali, Derrick Wing Kwan Ng +1
This paper considers the uplink of a cloud radio access network (C-RAN) comprised of several multi-antenna remote radio units (RUs) which send the data that they received from mult…
