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 ...
Study of the B +→ J / ψ Λ ¯ p decay in proton-proton collisions at √s = 8 TeV
(Springer, 2019-12-12)
A study of the B +→ J / ψ Λ ¯ p decay using proton-proton collision data collected at s = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb−1, is presented. The ratio of branching ...
Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at √s=8 TeV
(Springer Nature, 2018-03)
Results are presented from a search for natural gauge-mediated supersymmetry (SUSY) in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the lightest ...
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 ...
Search for t t ¯ H production in the H → b b ¯ decay channel with leptonic t t ¯ decays in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2019-03-05)
A search is presented for the associated production of a standard model Higgs boson with a top quark-antiquark pair (ttH), in which the Higgs boson decays into a b quark-antiquark pair, in proton-proton collisions at a ...
