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...

Design and performances evaluation of new Costas-based radar waveforms with pulse coding diversity

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

Costas codes are a variant of pulse compression waveforms, largely studied for their attractive time-frequency properties. Their 'thumbtack-like' ambiguity function (AF) makes them highly suitable for delay and Doppler estimation, in radar and sonar applications. However, this behaviour...

Experimental Study of Passive Defect Detection and Localization in Thin Plates from Noise Correlation

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada, Jamal Assaad, Farouk Benmeddour

This paper reports experimental results on a passive imaging technique for structural health monitoring to detect the occurrence of defects in plate-like structures. This technique is based on the fact that the active transient response between two sensors can be passively retrieved by cross-...

Bulk elastic waves with unidirectional backscattering-immune topological states in a time-dependent superlattice

N. Swinteck, S. Matsuo, K. Runge, Jerome O. Vasseur, P. Lucas, P. Deymier

Recent progress in electronic and electromagnetic topological insulators has led to the demonstration of one way propagation of electron and photon edge states and the possibility of immunity to backscattering by edge defects. Unfortunately, such topologically protected propagation of waves in the...

Ultra-foldable/stretchable wideband RF interconnects using laser ablation of metal film on a flexible substrate

Sofiene Bouaziz, Matthieu Berthomé, J.F. Robillard, Emmanuel Dubois

In this paper we demonstrate the feasibility of mechanically flexible and stretchable coplanar waveguide (CPW) transmission lines at millimeter-wave frequencies. Our approach is based on meander horseshoe-shaped CPW line on 125 mu m-thick Polyethylene Naphthalate (PEN) dielectric substrate. The...
