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 ...
Vehicular visible light communication with low beam transmitters in the presence of vertical oscillation
(IEEE, 2023-08)
The availability of light-emitting diodes (LEDs) in vehicle exteriors makes possible the use of visible light communication (VLC) as a vehicle-to-vehicle (V2V) wireless connectivity solution. While there has been a growing ...
Performance investigation of streetlight-to-vehicle visible light communication
(IEEE, 2023)
This paper investigates streetlight-to-vehicle visible light communication (VLC) system performance for outdoor broadcasting applications. We adopt streetlight lamps as optical internet-of-thing (IoT) devices broadcasting ...
Free space optical communication: An enabling backhaul technology for 6G non-terrestrial networks
(MDPI, 2023-11)
The deployment of non-terrestrial networks (NTNs) is envisioned to achieve global coverage for 6G and beyond. In addition to space nodes, aerial NTN nodes such as high-altitude platform stations (HAPSs) and rotary-wing ...
Optimal resource allocation and interference management for multi-user uplink light communication systems with angular diversity technology
(IEEE, 2020)
Light communication (LC) technology has been regarded as a promising candidate for future indoor wireless networks by providing safe, power-efficient, and high data rate communications needed for tomorrow's applications. ...
Experimental investigation of pointing errors on drone-based FSO systems
(IEEE, 2020-10-05)
Airborne free space optical (FSO) links can be efficiently used for backhaul/fronthaul needs of future cellular networks. Unlike terrestrial FSO links where a fixed connection between two buildings is considered, airborne ...
Limited feedback channel estimation for multi-user massive mimo visible light communications
(IEEE, 2020)
Building on the existing illumination infrastructure, visible light communication (VLC) utilizes light emitting diode (LED) luminaries as wireless access points. The presence of large number of ceiling lights in conference ...
