Operation altitude optimization of solar-powered rotary-wing UAVs for FSO backhauling
(IEEE, 2023)
Free space optical communication (FSO) has emerged as an alternative backhauling technology. It provides a line-of-sight (LOS) link with a capacity comparable to fiber optics and much higher than those that can be supported ...
Adaptive modulation for FSO IM/DD systems with multiple transmitters and receivers
(IEEE, 2023-02)
Atmospheric turbulence is a major impairment in free space optical (FSO) communication systems. Since turbulence induced fading exhibits quasi-static characteristics, reliable feedback of channel state information is ...
FSO link attenuation measurement in extreme winter conditions for secure 5G applications
(SPIE, 2023)
The functionality of Free Space Optical (FSO) communication links is highly influenced by meteorological conditions such as precipitation, snowfall, and fog. In this study, we establish an FSO link and conduct experimental ...
FPGA-based implementation of an underwater quantum key distribution system with BB84 protocol
(IEEE, 2023-08)
As threats in the maritime domain diversify, securing data transmission becomes critical for underwater wireless networks designed for the surveillance of critical infrastructure and maritime border protection. This has ...
Comparative characterization of indoor VLC and MMW communications via ray tracing simulations
(IEEE, 2023)
The demand for ultra-high-speed indoor wireless connectivity is ever-increasing, which poses unique challenges for the next generation wireless communication system design. This has prompted the exploration of higher ...
Joint lifetime-outage optimization in relay-enabled IoT networks—A deep reinforcement learning approach
(IEEE, 2023-01)
Network lifetime maximization in Internet of things (IoT) is of paramount importance to ensure uninterrupted data transmission and reduce the frequency of battery replacement. This letter deals with the joint lifetime-outage ...
Characterization of orbital angular momentum-multiplexed FSO channel in the presence of pointing errors
(IEEE, 2023)
Free space optical communication (FSO) uses laser transmitters at near-infrared wavelengths for line-of-sight wireless communication. Through the use of advanced laser beams instead of the conventional Gaussian-shaped beam, ...
Pilot-aided channel estimation for RIS-assisted wireless systems over time-varying fading channels
(IEEE, 2023)
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology for improving wireless communication system performance. RISs can adjust signals' phase and amplitude, resulting in improved signal strength. ...
FSO-based backhauling for airborne THz base stations
(IEEE, 2023)
Airborne nodes in the form of high-altitude platform stations (HAPSs) or unmanned aerial vehicles (UAVs) can be used for backhauling and wireless access. In this paper, we investigate the cascaded free space optical ...
Experimental demonstration of an FPGA-based outdoor VLC broadcasting system
(IEEE, 2023)
Visible light communication (VLC) uses light-emitting diodes (LEDs) to transmit data by turning them on and off at very high speeds, too fast for the human eye to perceive. In outdoor environments, LED-based streetlights ...
