Spectrum sensing applied to IR-UWB system based on M-OAM

Lamyae Maatougui, H. Ouahmane, A. Hajjaji, Khadija Hamidoun, Atika Rivenq, Yassin El Hillali

Intelligent transport system (ITS) exploits new communication and information technologies to make existing infrastructures more effective and more reliable, it resets on functions associated with the intelligence. The use of the ultra-wideband (UWB) appears as a very suitable technology for this...

A New Multi-user Ultra Wide Band System Based on Modified Gegenbauer Functions and M-OAM Modulation for Communication of Intelligent Transportation Systems

Khadija Hamidoun, Raja Elassali, Yassin El Hillali, Atika Rivenq, Khalid Elbaamrani, Fouzia Boukour

Ultra-wideband technology is based on the transmission of very short pulses with relatively low energy, which make it a promising option for short range wireless commu- nication system. In this paper, we propose to use this technology to establish a new multi- user technique dedicated to...

On the use of tracking loops for low-complexity multi-path channel estimation in OFDM systems

Huaqiang Shu, Eric Pierre Simon, Laurent Ros

—This paper treats pilot aided multi-path channel estimation with tracking loops for OFDM systems under slow to moderate fading conditions. Recent works have presented theoretical results for the tuning of second-order and third-order tracking loops in the particular context of Jakes's Doppler...

Optimization of a tunable piezoelectric resonator using phononic crystals with periodic electrical boundary conditions

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Piezoelectric phononic crystals with periodic short-circuit conditions exhibit Bragg band gaps. They are used to design a Fabry-Perot cavity. The design of the device enables a modification of cavity length by a spatial shift of electrical boundary conditions. The resonator is thus tunable and a...

Hexamolybdenum Clusters Supported on Graphene Oxide: Visible-Light Induced Photocatalytic Reduction of Carbon Dioxide into Methanol

Pawan Kumar, Harshal P. Mungse, Stéphane Cordier, Rabah Boukherroub, Om P. Khatri, Suman L Jain

Hexamolybdenum (Mo6) cluster-based compounds namely Cs2Mo6Bri8Bra6 and (TBA)2Mo6Bri8Bra6 (TBA = tetrabutylammonium) were immobilized on graphene oxide (GO) nanosheets by taking advantage of the high lability of the apical bromide ions with oxygen-functionalities of GO nanosheets. The loading of Mo6...

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in...

Non-contact ultrasonic non-destructive techniques : state of the art and their use in civil engineering

Mariusz Kaczmarek, Bogdan Piwakowski, Radoslaw Drelich

Ultrasonic methods of testing of civil engineering materials in air where both transmission of waves into materials and reception of signals are contactless are reviewed. Short history, technical details and examples of applications of currently available methods are discussed. Keywords: ultrasound...

Dispersion curves of 2D rods with complex cross-sections: double orthogonal polynomial approach

J.G. Yu, Jean-Etienne Lefebvre, Ch. Zhang, Faniry Emilson Ratolojanahary

Orthogonal polynomial series approach has been used to analyze the guided wave propagation in structures for about 20 years. These structures have always one infinite dimension in the waveguiding direction and, sometimes a regular finite cross-section (axially infinite solid or hollow cylinder for...

A model to predict modal radiation by finite-sized sources in composite plates with account of caustics

Mathilde Stévenin, Alain Lhémery, Sébastien Grondel

The guided wave field generated by finite size transducers in a composite plate is studied. For isotropic plates, Fraunhofer-like approximations can be found in the literature. Similar approximations fail when the plate is anisotropic. A new calculation method is proposed. Based on a modal...
