Third-order Complex Amplitudes Tracking Loop for Slow Fading Channel Estimation

Huaqiang Shu, Laurent Ros, Eric Pierre Simon

This paper deals with channel estimation over a flat fading Rayleigh channel with Jakes' Doppler Spectrum. Many estimation algorithms exploit the time-domain correlation of the channel by employing a Kalman filter based on a first-order (or sometimes second-order) approximation of the time-...

The parametric propagation in underwater acoustics : experimental results

Etienne Bouttard, Valérie Labat, Olivier Bou Matar, Thierry Chonavel

In underwater acoustics, detection of buried objects in sediments (cables, mines, . . . ) is a complex problem. Indeed, in order to ensure sufficient penetration depth in marine sediments, low frequencies have to be used, implying a low resolution. A solution proposed to solve this problem is the...

Caractérisation ultrasonore de structures à couche et à gradient de contraintes par ondes de surface haute fréquence générées par capteurs MEMS de type IDT -SAW, No title in english

Julien Deboucq

L’utilisation de revêtements et de couches minces déposés sur substrats est très recherchée dans de nombreuses applications. Les objectifs de ces revêtements et dépôts sont multiples (améliorer la durabilité des structures, leur résistance à l’usure et à la fatigue, etc.). D'autre part, les..., The use of coatings and thin layers deposited on substrates is highly sought in many applications. The objectives of these coatings and deposits are multiple (improve the durability of structures, their wear resistance and fatigue, etc.). On the other hand, gradient materials are being developed to...

Photoassisted Fowler-Nordheim-like tunneling from passivated GaAs microcantilevers

D. Paget, A. Rowe, S. Arscott, Emilien Peytavit

We have investigated the mechanisms of photoelectron tunneling into gold from tipless, nitridized, gallium arsenide microcantilevers through thin polymers. A study of the tunnel bias, tunnel distance, and light excitation power dependence of the tunneling photo-current reveals the tunneling process...

Surface and intrinsic conduction properties of Au-catalyzed Si nanowires

Lukasz Borowik, Ileana Florea, D. Deresmes, Ovidiu Ersen, D. Hourlier-Bahloul, Thierry Melin

An original atomic force microscopy (AFM) method is used to probe surface conduction properties of Au-catalyzed (111) oriented Si nanowires (NWs) attached on the substrate on which they were grown. Drastically different transport regimes are observed upon tuning the electronic junction between the...
