Power Domain NOMA Without SIC in Downlink CSS-Based LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Ido Nevat, Laurent Clavier

Low Power Wide Area Network, such as LoRa is one of the main building blocks of the Internet of Things. One of the main issues is to scale up the number of devices and one strong limitation comes from the downlink communication. In fact, the access point is constrained by the duty cycle, therefore…

Full-duplex relaying for opportunistic spectrum access under an overall power constraint

Anne Savard, Elena Veronica Belmega

To meet the bold requirements of future generation networks, emerging technologies such as opportunistic spectrum access, multi-tier networks, full-duplexing and cooperative networks have to be exploited. In this paper, we propose to blend all the above and globally optimize a relay-aided cognitive…

Quantification of the adhesion of metal thin film interfaces by picosecond acoustics

Alejandro Vital Juarez, Arnaud Devos, Jean-Michel Desmarres

Thin films are widespread in numerous fields: engineering, electronics, optics, biomedical, space and many more. They are largely used and require a flawless quality. One of the most important parameters is the adhesion of a layer with the substrate. Different methods of measuring the adhesion are…

[Invited] Miniaturisation du stockage électrochimique de l'énergie : vers la fabrication de micro-batteries performantes tout solide

Christophe Lethien

La miniaturisation des objets connectés impose la fabrication de sources de stockage d’énergie de plus en plus petites. A ce titre, la fabrication de batteries miniatures tout solide (appelées micro-batteries) performantes est un challenge scientifique où la tendance est de passer d’une technologie…

Millimeter wave carbon nanotube based flip chip coplanar interconnects

Joseph de Saxce, Philippe Roux-Levy, Chun Fei Siah, Jianxiong Wang, Beng Kang Tay, Philippe Coquet, Dominique Baillargeat

In this work, we investigate the performances of vertically aligned carbon nanotube (VACNT) arrays for high frequency interconnects. The frequency range of this study is the W band (75 GHz to 110 GHz). The type of interconnect is coplanar, meaning the interconnect can connect two subparts…
