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 ...
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 ...
Development of an aerial interface for extraction of the electrodynamic fingerprints of the single-photon detectors
(Wiley, 2021-12)
In this study, a novel structure of semi array of antipodal Vivaldi antenna is designed to extract the RF radiations from the single-photon detectors in a quantum key distribution system. The proposed antenna covers a ...
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 ...
16-elements helical antenna system integration with a solar cell powered IoT collector
(IEEE, 2019)
An 868MHz-915MHz 16-elements helical wire antenna array design with a solar-cell integration is presented. Each element is designed to be omni-directional with the corresponding tuning stubs and ground substrate. This is ...
Comments on “A set square design metamaterial absorber for X band applications”
(Taylor & Francis, 2021-05-24)
In a recently published paper, Chetan Barde et al. [Barde C, Choubey A, Sinha R. A set square design metamaterial absorber for X-band applications. J Electromagn Waves Appl. 2019:1–14.] have proposed a wideband metamaterial ...
