Energy-efficient 1-bit feedback NOMA in wireless networks with no CSIT/CDIT

Hajar El Hassani, Anne Savard, E Veronica Belmega

In this paper, the energy efficiency of a two-user downlink non-orthogonal multiple access (NOMA) system is investigated. We consider a stochastic time-varying channel that is unknown at the transmitter side (in state and distribution) and propose an online learning method that is energy efficient…

Joint modeling of received power, mean delay, and delay spread for wideband radio channels

Ayush Bharti, Ramoni Adeogun, Xuesong Cai, Wei Fan, Francois-Xavier Briol, Laurent Clavier, Troels Pedersen

We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different…

Zero on site testing of railway wireless systems: the Emulradio4Rail platforms

Marion Berbineau, Ali Sabra, Virginie Deniau, Christophe Gransart, Raul Torrego, Aitor Arriola, Inaki Val, Jose Soler, Ying Yan, Alessandro Vizzarri, Franco Mazzenga, Sofiane Kharbech, Laurent Clavier, Rédha Kassi, Juan Moreno Garcia-Loygorri

The European Train Control System (ETCS) relies today on the 2nd generation cellular system GSM-R. GSM-R obsolescence has triggered the evolution of the current European Railway Traffic Management System (ERTMS) to the Future Railway Mobile Communication System (FRMCS), under development. FRMCS…

Towards the use of flapping wing nano aerial vehicles

Sébastien Grondel, Mathieu Colin, Marie Zwingelstein, Sofiane Ghenna, Caroline Soyer, Eric Cattan, Olivier Thomas

In the last decade, the potential of Micro Aerial Vehicles (MAVs) has generated an enormous interest in this technology and numerous applications have therefore been proposed in military and civilian fields. More recently, researchers have begun to work on a new and miniaturized generation called…

ESD mm-wave-circuit protection: 3-dB couplers

Marc Margalef-Rovira, Géraldine Pelletier, Vanessa Avramovic, Sylvie Lepilliet, Johan Bourgeat, Jean-Marc Duchamp, Manuel J. Barragan, Emmanuel Pistono, Sylvain Bourdel, Christophe Gaquière, Philippe Ferrari

This article presents an innovative architecture for the implementation of an electrostatic discharge (ESD) protection for millimeter-wave (mm-wave) devices. The proposed architecture is based on the use of 3-dB couplers, whose coupled outputs have been shorted to the ground node. In order to…

Experimental realization of a pillared metasurface for flexural wave focusing

Wan Wang, Julio Andrés Iglesias Martinez, Yabin Jin, Bahram Djafari-Rouhani, Abdelkrim Khelif

A metasurface is an array of subwavelength units with modulated wave responses that show great potential for the control of refractive/reflective properties in compact functional devices. In this work, we propose an elastic metasurface consisting of a line of pillars with gradient heights, erected…
