EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)
In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ...
Aperture averaging in multiple-input single-output free-space optical systems
(SPIE, 2015-06)
Multiple-input single-output systems are employed in free-space optical links to mitigate the degrading effects of atmospheric turbulence. We formulate the power scintillation as a function of transmitter and receiver ...
Emerging optical wireless communications-advances and challenges
(IEEE, 2015-09)
New data services and applications are emerging continuously and enhancing the mobile broadband experience. The ability to cope with these varied and sophisticated services and applications will be a key success factor for ...
Ultraviolet communications for ground-to-air links
(IEEE, 2019)
Ultraviolet (UV) communication enables non-line-of-sight (NLOS) wireless connectivity through strong molecular and aerosol scattering. Due to their NLOS nature, UV links bring robustness to blockage or shadowing and relax ...
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
(IEEE, 2010)
In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study ...
A machine learning approach for mechanism selection in complex negotiations
(Springer Nature, 2018-04)
Automated negotiation mechanisms can be helpful in contexts where users want to reach mutually satisfactory agreements about issues of shared interest, especially for complex problems with many interdependent issues. A ...
Visible light communications: from theory to industrial standardization
(IEEE, 2019)
Visible light communication (VLC) builds upon the ubiquitous presence of LEDs and exploits the existing illumination infrastructure for wireless access. VLC provides high data rate transmission in unregulated optical ...
A new boson with a mass of 125 GeV observed with the CMS experiment at the large hadron collider
(American Association for the Advancement of Science, 2012-12-21)
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2014-06)
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
Multiplicity and rapidity dependence of strange hadron production in pp, pPb, and PbPb collisions at the LHC
(Elsevier, 2017-05-10)
Measurements of strange hadron (K-S(0), Lambda +(Lambda) over bar, and Xi(-)+(Xi) over bar (+)) transverse momentum spectra in pp, pPb, and PbPb collisions are presented over a wide range of rapidity and event charged-particle ...
