Experimental investigation of lens combinations on the performance of vehicular VLC
(IEEE, 2020)
With the increasing adoption of LEDs in outdoor light sources such as traffic lights, street lights and vehicle headlamps, visible light communication (VLC) has the promise to become a major enabler for vehicle-to-vehicle ...
Performance analysis and optimization of unipolar OFDM based relay-assisted visible light communications☆☆
(Elsevier, 2017)
In this paper, we consider a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source. Following the IEEE 802.15.7r1 VLC reference channel model, we ...
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 ...
Experimental characterization of multi-hop vehicular VLC systems
(IEEE, 2021)
In vehicular visible light communication (VLC), the reliable communication distance may be relatively short due to its dependence on many factors including the weather condition. This necessitates the use of relay-assisted ...
Flexible generalized spatial modulation for visible light communications
(IEEE, 2021-01)
Adaptive spatial modulation (ASM) varies the modulation size across the transmit light-emitting diodes (LEDs) to improve the overall spectral efficiency of visible light communication (VLC) systems. This article proposes ...
Efficient resource allocation scheme for multi-user hybrid VLC/IR networks
(IEEE, 2019)
An optimal fair resource allocation (OFRA) scheme is proposed to mitigate both inter-symbol and inter-user interferences in uplink multi-user VLC/IR networks. The scheme aims to improve the fairness among the users in terms ...
A new LED response model and its application to pre-equalization in VLC systems
(IEEE, 2021-09-01)
With the growing interest in visible light communication (VLC), it is desired to transmit data at very high rates despite the LED's bandwidth becoming a bottleneck. The bandwidth of a white LED usually ranges between ...
AUV trajectory optimization for an optical underwater sensor network in the presence of ocean currents
(IEEE, 2021)
Autonomous underwater vehicles (AUVs) are instrumental for data offloading in underwater sensor networks (USNs). With high data rate capacity at transmission ranges in the order of several tens of meters, visible light ...
Vehicular VLC channel model for a low-beam headlight transmitter
(IEEE, 2021-09-06)
The availability of LED-based headlights and taillights allows visible light communication (VLC) to be considered as a powerful wireless access technology for vehicle-to-vehicle (V2V) communications. A crucial system design ...
Comparative performance evaluation of VLC, LTE and WLAN technologies in indoor environments
(IEEE, 2021)
Recent years have seen an exponential rise in the demand for indoor wireless connections that have driven future generation networks to aim for higher data rates with extended coverage and affordable rates. The two most ...
