SVM Assisted Primary User-Detection for Non-Cooperative Cognitive Radio Networks

Kais Bouallegue, Matthieu Crussière, Sofiane Kharbech

This paper presents a new blind spectrum sensing (SS) algorithm based on a machine learning model: the radial basis function support-vector machines (RBF-SVM). As features, the introduced approach uses statistical tests that are based on the eigenvalues of the received signals covariance matrix.…

Purification for Carbon Nanotubes Synthesized by Flame Fragments Deposition via Hydrogen Peroxide and Acetone

Asmaa Hammadi, Ahmed Jasim, Firas Abdulrazzak, Abdulkareem Al-Sammarraie, Yacine Cherifi, Rabah Boukherroub, Falah Hussein

Carbon nanotubes (CNTs) are synthesized by the flame fragment deposition (FFD) technique using Iraqi liquefied petroleum gas (LPG) as a source of carbon in a hand-made reactor at a low temperature (160 °C) without using a catalyst. Purification of the multi-walled carbon nanotubes (MWCNTs) is…

Investigation of resistive switching and transport mechanisms of Al ₂O₃/TiO_2−<i>x</i> memristors under cryogenic conditions (1.5 K)

Yann Beilliard, François Paquette, Frédéric Brousseau, Serge Ecoffey, F. Alibart, Dominique Drouin

Resistive switching and transport mechanisms of Al2O3/TiO2−x memristor crosspoint devices have been investigated at cryogenic temperatures down to 1.5 K, for the future development of memristor-based cryogenic electronics. We report successful resistive switching of our devices in the temperature…

Frequency-domain simulation of power electronic systems based on multi-topology equivalent sources modelling method

Stephane Vienot, Arnaud Videt, Nadir Idir, Lamine Kone, Sebastien Weiss, Frederic Lafon

ElectroMagnetic Interference (EMI) simulation of power converters helps engineers in the design process. In this paper, we describe a frequency-domain simulation method based on the Multi-Topology Equivalent Sources (MTES) model. The aim is to reproduce the non-linear behavior of power switches for…

Smart way to adjust Schottky barrier height in 130 nm BiCMOS process for sub-THz applications

Vincent Gidel, Frederic Gianesello, Pascal Chevalier, Gregory Avenier, Nicolas Guitard, Michel Buczko, Cyril Luxey, Guillaume Ducournau

In this paper, an innovative Schottky diode architecture is proposed and implemented in 130 nm BiCMOS technology. A state-of-the-art 1 THz cut-off frequency is measured and an innovative way to modify the height of the Schottky barrier is proposed. This smart way could enable zero-bias high-…

Robust Fano resonance in a topological mechanical beam

Wei Wang, Yabin Jin, Wan Wang, Bernard Bonello, Bahram Djafari-Rouhani, Romain Fleury

The advances in topological condensed matter physics enable the manipulation of classic waves in different ways, such as unidirectional propagation featuring the suppression of backscattering and the robustness against impurities and disorder, making it possible to endow classical phenomena with…

Power-efficient reliable register file for aggressive-environment applications

Ihsen Alouani, Hamzeh Ahangari, Özcan Özturk, Smail Niar

In a context of increasing demands for on-board data processing, insuring reliability under reduced power budget is a serious design challenge for embedded system manufacturers. Particularly, embedded processors in aggressive environments need to be designed with error hardening as a primary goal,…

Effect of substrate moisture content on sound absorption by green systems

Emmanuel Attal, Nicolas Côté, Takafumi Shimizu, Bertrand Dubus

Sound and noise reflections from acoustically rigid materials constituting buildings and roads contribute strongly to acoustic environment in urban areas. Building envelope greening which improves noticeably sound absorption, may be a solution for acoustic protection in cities when applied in a…

Performance analysis of UFMC waveform in graded index fiber for 5G communications and beyond

Mahdi Kasmi, Sofien Mhatli, Faouzi Bahloul, Iyad Dayoub, Kyunghwan Oh

For the first time, we demonstrate in this paper an intensity-modulation direct-detection (IMDD) universal filtered multi-carrier (UFMC) system through several hundred meters of multimode fiber (MMF) that can be adopted for 5G communications and beyond. The proposed system is simulated and…
