Coverage analysis of downlink MU-MIMO cellular networks
(IEEE, 2021-09)
In this letter, we analyze the coverage performance of multi-user multiple-input multiple-output (MU-MIMO) downlink cellular networks. We model the locations of the base stations and mobile users using Poisson Point Processes ...
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 ...
Magnitude and wrap-phase OFDM for MIMO visible light communication systems
(IEEE, 2021-07)
Generalized light emitting diode (LED) index modulation (GLIM) has been proposed as an effective multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) scheme for visible light communications ...
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)
Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ...
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 ...
Visible light communication for connected vehicles: How to achieve the omnidirectional coverage?
(IEEE, 2021)
Visible light communication (VLC) is based on the idea of modulating the light intensity of LEDs to transmit information and enables the dual use of exterior automotive and road side infrastructure lighting for both ...
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 ...
A cross-layer design for dynamic resource management of VLC networks
(IEEE, 2021-03)
In this article, we propose a cross-layer resource management mechanism for an indoor multiuser visible light communication (VLC) access network. The physical layer builds upon DC-biased orthogonal frequency division ...
Comprehensive study on UAV-based FSO links for high-speed train backhauling
(The Optical Society, 2021-09-20)
In this paper, we introduce the idea of using unmanned aerial vehicle (UAV)-based free-space optical communication systems to backhaul high-speed trains. We introduce a composite channel model that includes effects of both ...
