Ultraviolet communications for unmanned aerial vehicle networks
(IEEE, 2022)
Due to the strong scattering, ultraviolet (UV) communication links enable non-line-of-sight (NLOS) outdoor connectivity and relax the pointing, acquisition, and tracking requirements encountered in infrared links. This ...
Distributed MIMO for Li-Fi: Channel measurements, ray tracing and throughput analysis
(IEEE, 2021-08-15)
LiFi has been considered as a promising candidate for future wireless indoor networks. The IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models generated using the non-sequential ray tracing ...
Efficient resource allocation scheme in multi-user liFi networks based on angle oriented transceiver
(IEEE, 2021)
In this paper, an efficient resource allocation scheme in multi-user LiFi networks is proposed using the angle oriented (AO) technology at the receiver and transmitter sides. To cope with the inter-symbol and inter-user ...
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 ...
