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…

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…

Joint estimation of state and noise parameters in a linear dynamic system with impulsive measurement noise: Application to OFDM systems

Nouha Jaoua, Emmanuel Duflos, Philippe Vanheeghe, Laurent Clavier, François Septier

Interference mitigation is one of the main challenges in wireless communication, especially in ad hoc networks. In such context, the Multiple Access Interference (MAI) is known to be of an impulsive nature. Therefore, the conventional Gaussian assumption is inadequate to model this type of…

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…

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…

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…

Temperature dependence of the conduction mechanisms through a Pb(Zr,Ti)O3 thin film

C. Jegou, L. Michalas, T. Maroutian, G. Agnus, M. Koutsoureli, G. Papaioannou, L. Largeau, David Troadec, A. Leuliet, P. Aubert, P. Lecoeur

The conduction mechanisms through a lead zirconate titanate (PZT) thin film grown by pulsed laser deposition with a La0.67Sr0.33MnO3 (LSMO) buffer layer on epitaxial Pt (111) were assessed in the 230-330 K temperature range. X-Ray diffraction and transmission electron microscopy evidenced a…

Millimeter-wave in situ tuner : an efficient solution to extract the noise parameters of SiGe HBTs in the whole 130-170 GHz range

Marina Deng, Laurent Poulain, Daniel Gloria, Thomas Quémerais, Pascal Chevalier, Sylvie Lepilliet, Francois Danneville, Gilles Dambrine

SiGe HBT noise parameters ( , and ) are for the first time extracted in the entire 130 - 170 GHz frequency range. This achievement is realized using a D-band on-chip source-pull system, which includes an impedance tuner integrated with the transistor under test. On-wafer noise power measurements on…
