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 ...
A comparative evaluation of propagation characteristics of vehicular VLC and MMW channels
(IEEE, 2023)
Vehicle-to-vehicle (V2V) communication is an underlying key technology to realize future intelligent transportation systems. Both millimeter wave (MMW) communication and visible light communication (VLC) are strong candidates ...
Implementation of software-defined adaptive DCO-OFDM for vehicular visible light communication
(IEEE, 2023)
With its high data rates and electromagnetic interference-free operation capability, visible light communication (VLC), has emerged as a potential candidate for 6G and beyond networks. In this work, we present the preliminary ...
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 ...
IEEE 802.11BB reference channel models for light communications
(IEEE, 2023-12-01)
Increasing industrial attention to visible light communications (VLC) technology led the IEEE 802.11 to establish the task group 802.11bb 'Light Communications' (LC) for the development of a VLC standard. As a part of the ...
Optimal resource allocation and interference management for multi-user uplink light communication systems with angular diversity technology
(IEEE, 2020)

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 ...
