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 ...
Battery integrated off-grid DC fast charging: Optimised system design case for California
(IEEE, 2021)
Global acceptance and exploitation of electric vehicles (EV) is no doubt a fact. There are two major factors beneath this growth; 1. increasing battery capacity thus rising range and 2. availability of DC fast charging ...
Minimizing cogging torque in permanent magnet synchronous generators for small wind turbine applications
(Gazi University, 2021-06)
Permanent magnet synchronous generators have a wide usage among electric machines, especially in small wind turbine systems. However permanent magnet synchronous generators suffer from cogging torque due to the magnetic ...
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 ...
Effect of photon statistics on vacuum fluctuations based QRNG
(IOP Publishing, 2021-06)
The speed of quantum random number generators (QRNGs) is a major concern for practical applications. In this work, we introduce scattering as a method to enhance the randomness characteristics of the entropy source. This ...
