Experimental evaluation of a software defined visible light communication system
(IEEE, 2020)
Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for illumination and communication purposes. With its large bandwidth and immunity to electromagnetic interference, VLC can be used as ...
Multi-hop quantum key distribution with passive relays over underwater turbulence channels
(The Optical Society, 2020-12-01)
Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communication links. In this paper, as a potential solution to overcome range limitations, we investigate a ...
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 ...
Channel measurements and ray tracing simulations for MIMO light communication at 200 MHz
(IEEE, 2020-09)
In this paper, we investigate 2 × 2 MIMO light communication channels using non-sequential ray tracing simulations, and measurements over 200 MHz bandwidth using a MIMO channel sounder. Results indicate good agreement ...
Hybrid LiFi/MMW wireless communication system with adaptive vertical handover capability
(IEEE, 2020-10-05)
Millimeter wave (MMW) communication was proposed as a high-bandwidth wireless access solution to cope with the increasing user demand for mobile data and has been already standardized in 5G networks. As another highcapacity ...
Vehicular visible light communications: The impact of taillight radiation pattern
(IEEE, 2020-09)
We investigate the path-loss of vehicular visible light communications based on the radiation pattern of a commercial car taillight. The measured pattern is incorporated into a ray-tracing model and simulation results ...
Opto-electronic receiver system with post-equalization for visible light communications
(IEEE, 2020-10-05)
In this work, A significant increase in the data rate is achieved by designing an opto-electronic receiver for the visible light communication system. LEDs used at the transmitter side in the visible light communication ...
