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 ...
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 ...
DMT analysis and optimal scheduling for two-hop parallel relay networks
(Elsevier, 2021-06)
Two-hop parallel networks with half-duplex relays over quasi-static Rayleigh fading channels are considered. Assuming relays have only local channel state information, optimal communication schemes for these networks in ...
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 ...
Characterization of LEDs for visible-light communications
(SPIE, 2021-02)
Recent advances in solid-state technologies have enabled the development of light-emitting diodes (LEDs) with favorable features such as long life expectancy, low-power consumption, and reduced heat dissipation. Visible-light ...
Effect of scattering phase function on underwater visible light communication channel models
(Elsevier, 2021-10)
Non-sequential ray tracing simulations are commonly employed to model underwater visible light communication (VLC) channels. The accuracy of such simulations highly depends on how well the optical properties of water (i.e., ...
