Covert Capacity of Non-Coherent Rayleigh-Fading Channels

Mehrdad Tahmasbi, Anne Savard, Matthieu Bloch

The covert capacity is characterized for a non-coherent fast Rayleigh-fading wireless channel, in which a legitimate user wishes to communicate reliably with a legitimate receiver while escaping detection from a warden. It is shown that the covert capacity is achieved with an amplitude-constrained...

Joint channel estimation and data detection for OFDM based cooperative system

Mokhtar Besseghier, Ahmed Bouzidi Djebbar, Abdelhak Zouggaret, Iyad Dayoub

Orthogonal frequency division multiplexing based cooperative system using Alamouti space–time block coding at relay node represents an alternative solution to achieve better connectivity and significant enhancement to the data rate in wireless fading channels. But, these advantages cannot be...

Acoustic demultiplexer based on Fano and induced transparency resonances in slender tubes star star star

Abdelkader Mouadili, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We give an analytical demonstration of the possibility to realize a simple phononic demultiplexer based on Fano and acoustic induced transparency resonances. The demultiplexer consists of a Y-shaped waveguide with an input line and two output lines. Each output line contains two stubs grafted...

Surface spin magnetism controls the polarized exciton emission from CdSe nanoplatelets

Elena V Shornikova, Aleksandr A Golovatenko, Dmitri R Yakovlev, Anna V Rodina, Louis Biadala, Gang Qiang, Alexis Kuntzmann, Michel Nasilowski, Benoit Dubertret, Anatolii Polovitsyn, Iwan Moreels, Manfred Bayer

The surface of nominally diamagnetic colloidal CdSe nanoplatelets can demonstrate para-magnetism owing to the uncompensated spins of dangling bonds (DBSs). We reveal that by optical spectroscopy in high magnetic fields up to 15 Tesla using the exciton spin as probe of the surface magnetism. The...

Unravelling local environments in mixed TiO2–SiO2 thin films by XPS and ab initio calculations

Pavel Ondračka, David Nečas, Michèle Carette, Stéphane Elisabeth, David Holec, Agnès A. Granier, Antoine Goullet, Lenka Zajíčková, Mireille Richard-Plouet

Mixed TixSi1−xO2 oxide can exhibit a partial phase separation of the TiO2 and SiO2 phases at the atomic level. The quantification of TiO2-SiO2 mixing in the amorphous material is complicated and was so far done mostly by infrared spectroscopy. We developed a new approach to the fitting of X-ray...

Temperature compensated magnetic field sensor based on Love waves

Harshad Mishra, Jérémy Streque, Michel Hehn, Prince Mengue, Hamid M'Jahed, Daniel Lacour, Karine Dumesnil, S. Petit-Watelot, Sergei Zhgoon, Vincent Polewczyk, Aurélien Mazzamurro, Abdelkrim Talbi, Sami Hage-Ali, Omar Elmazria

A temperature compensated magnetic field sensor based on the combination of CoFeB ferromagnetic thin films and Quartz/ZnO Love waveguide platform is developed and optimized. The Love wave is a shear horizontal guided wave and therefore provides an optimal interaction with magnetisation in the...

Giant Magnetoelastic Coupling in a Love Acoustic Waveguide Based on TbCo 2 /FeCo Nanostructured Film on ST-Cut Quartz

Aurélien Mazzamurro, Yannick Dusch, Philippe Pernod, Olivier Bou Matar, Ahmed Addad, Abdelkrim Talbi, Nicolas Tiercelin

In this work, we propose a theoretical and experimental investigation of the interaction of guided pure shear horizontal (SH) wave within a uniaxial multilayered TbCo2/FeCo thin film deposited on Quartz ST-90°X cut in a delay line configuration. We evaluate theoretically the evolution of phase...

Emulation of various radio access technologies for zero on site testing in the railway domain - the Emulradio4rail platforms

Marion Berbineau, Juan Moreno, Sofiane Kharbech, Ying Yang, Alessandro Vizzari, Raul Torrego, José Soler, Laurent Clavier, Rédha Kassi, Franco Mazzenga, Romeo Giuliano, Val Inaki, Christophe Gransart, Virginie Deniau, Yann Cocheril, Kristina Svensson, Armano Carillo

In order to assess the reliability, availability, and maintainability of wireless links for the rail sector in the laboratory, it is necessary to develop measurement platforms able to emulate real railway radio environments. This type of testing platform should combine very new approaches, the so-...

Cross-Layer CNN Approximations for Hardware Implementation

Karim Mohamed Abedallah Ali, Ihsen Alouani, Abdessamad Ait El Cadi, Hamza Ouarnoughi, Smail Niar

Convolution Neural Networks (CNNs) are widely used for image classification and object detection applications. The deployment of these architectures in embedded applications is a great challenge. This challenge arises from CNNs’ high computation complexity that is required to be implemented on...
