Multiple-Antenna Based Blind Spectrum Sensing in the Presence of Impulsive Noise

Kais Hassan, Roland Gautier, Iyad Dayoub, Marion Berbineau, Emanuel Radoi

Cognitive radio was proposed as a solution to the spectrum scarcity problem. One of the basic functions of any cognitive radio is the spectrum sensing. Most of the existing works on spectrum sensing consider the Gaussian noise assumption. In practice, this assumption is not always valid since…

Electronic and physico-chemical properties of nanometric boron delta-doped diamond structures

Gauthier Chicot, Alexandre Fiori, P.N. Volpe, Thu Nhi Tran Thi, Jean-Claude Gerbedoen, Jessica Bousquet, M.P. Alegre, J.C. Pinero, D. Araujo, F. Jomard, Ali Soltani, Jean-Claude de Jaeger, J. Morse, J. Härtwig, Nicolas Tranchant, C. Mer-Calfati, Jean-Charles Arnault, Julien Delahaye, Thierry Grenet, David Eon, Franck Omnès, Julien Pernot, Etienne Bustarret

Heavily boron doped diamond epilayers with thicknesses ranging from 40 to less than 2 nm and buried between nominally undoped thicker layers have been grown in two different reactors. Two types of [100]-oriented single crystal diamond substrates were used after being characterized by X-ray white…

Dual mechanical behaviour of hydrogen in stressed silicon nitride thin films

F. Volpi, M. Braccini, Arnaud Devos, G. Raymond, A. Pasturel, Pascal Morin

In the present article, we report a study on the mechanical behaviour displayed by hydrogen atoms and pores in silicon nitride (SiN) films. A simple three-phase model is proposed to relate the physical properties (stiffness, film stress, mass density, etc.) of hydrogenated nanoporous SiN thin films…

Incertitudes des traitements des lésions hépatiques en radiothérapie stéréotaxique avec asservissement à la respiration

Marie Charoy

Le Centre Oscar Lambret traite avec le Cyberknife®, depuis juin 2007, les lésions hépatiques en conditions stéréotaxiques, avec un asservissement à la respiration par des repères externes corrélés à des grains implantés près de la cible. Les résultats cliniques montrent un excellent contrôle local…

On detection method for soft iterative decoding in the presence of impulsive interference

Vincent Dimanche, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance improvement of soft iterative decoders in impulsive interference modeled by additive noise. In case of $alpha$-stable noise, the inputs of the belief propagation decoder are too complex to compute. We propose to use an approximation of the log likelihood ratio…

Temperature dependence of dynamic hysteresis behavior in Pb0.4Sr0.6TiO3 ferroelectric films

Kui Li, Tao Li, Gang Du, Denis Remiens, Xianlin Dong, Genshui Wang

The temperature (T) dependence of dynamic hysteresis behavior is investigated in low temperature crystallized Pb0.4Sr0.6TiO3 thin films between 85 K and 340 K. It was found that the temperature scaling relations for hysteresis area 〈A〉, remnant polarization Pr and coercive field Ec take the…

Monte Carlo study of low and high-field electron transport in GaN-based heterostructures

Jean-Luc Thobel, François Dessenne, Christophe Dalle

Electron transport properties of GaN-based heterostructures are investigated by means of a Monte Carlo model, which considers a large number of subbands in several valleys. Room-temperature low-field mobility consistent with experimental results is obtained provided that screening of phonon…

Geometrical optics-based model for dielectric constant and loss tangent free-space measurement

Kamel Haddadi, Tuami Lasri

A microwave free-space reflection method for determining the complex permittivity of planar dielectric materials is demonstrated. The method makes use of the measurement of the near-field microwave reflection coefficient of a metal-backed sample. The modeling of the structure and its calibration…

MIMO and diversity techniques in tunnels

M. Lienard, Pierre Degauque, J.M. Molina-Garcia-Pardo, C. Sanchis-Borras

To improve the performances of a communication link, both in terms of capacity and bit error rate, MIMO technique is a solution which has been widely studied. However, in road or railway tunnels, the waves are guided by the structure and the angular spread of the rays, both at the transmitting side…
