Joint Carrier Frequency Offset and Channel Estimation for OFDM Systems via the EM Algorithm in the Presence of Very High Mobility

Eric Pierre Simon, Laurent Ros, Hussein Hijazi, Mounir Ghogho

In this paper, the problem of joint carrier frequency offset (CFO) and channel estimation for OFDM systems over the fast time-varying frequency-selective channel is explored within the framework of the expectation-maximization (EM) algorithm and parametric channel model. Assuming that the path…

Characterization and Modeling of Graphene Transistor Low-Frequency Noise

Brice Grandchamp, Sebastien Fregonese, Cédric Majek, Cyril Hainaut, Cristell Maneux, Nan Meng, Henri Happy, Thomas Zimmer

This brief presents low-frequency noise measurements on a graphene field-effect transistor with graphene layer decomposed from SiC substrate. The measurements indicate the predominance of flicker noise in the current noise source measured between drain and source with quadratic dependence with a…

Transport Inefficiency in Branched-Out Mesoscopic Networks: An Analog of the Braess Paradox

M. G. Pala, S. Baltazar, Peng Liu, Hermann Sellier, B. Hackens, F. Martins, Vincent Bayot, X. Wallart, L. Desplanque, Serge Huant

We present evidence for a counterintuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks. A numerical simulation of quantum transport in a two-branch mesoscopic network reveals that adding a third branch can paradoxically…

Robustness of high-resolution channel parameter estimators in presence of dense multipath components

Emmeric Tanghe, Davy Gaillot, Wout Joseph, M. Lienard, Pierre Degauque, Luc Martens

The estimation accuracy of specular multipath components in radio channels that include dense multipath is investigated. Classical multipath estimation algorithms such as ESPRIT and SAGE do not include dense multipath in their signal model whereas recent ones, such as RiMAX, do. These estimation…

Investigation of indium nitride for micro-nanotechnology

Anisha Gokarna, Jean-Francois Lampin, Dominique Vignaud, El Hadj Dogheche, Didier Decoster, Sandra Ruffenach, Olivier Briot, Matthieu Moret

We present a study of non–intentionally doped InN epilayers directly grown on sapphire substrate by metal organic chemical vapour deposition (MOCVD) technique. Structural and optical characterisations of this sample have been conducted by SEM, temperature–dependent photoluminescence and time…
