"Can you hear me now?" : Automatic assessment of background noise intrusiveness and speech intelligibility in telecommunications

This thesis deals with signal-based methods that predict how listeners perceive speech quality in telecommunications. Such tools, called objective quality measures, are of great interest in the telecommunications industry to evaluate how new or deployed sy ...

Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Andrew Charles Mallory Austin

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...

An overview of W-BAN antennas designed at LEMA

Anja Skrivervik

W-BAN applications have been around since a long time, but have been experiencing a tremendous growth during the last decades. This results in the need of dedicated antennas, which are designed and optimized taking into account their lossy surroundings. De ...

Design, Realization, and Experimental Test of a Coaxial Exponential Transmission Line Adaptor for a Half-Impulse Radiating Antenna

Farhad Rachidi-Haeri, Nicolas Mora Parra

This paper describes the simulation, design, realization, and experimental test of a tapered transmission line (TL) for adapting a broad-band impulse generator to a radiating antenna, for a frequency range of 50 MHz-1 GHz. Two different taper geometries ar ...

Experiment-Driven Characterization of Full-Duplex Wireless Systems

We present an experiment-based characterization of passive suppression and active self-interference cancellation mechanisms in full-duplex wireless communication systems. In particular, we consider passive suppression due to antenna separation at the same ...

Miniature Short-Stroke Linear Actuator

Yves Perriard, Grégory Savioz

This Article Addresses the Design and optimization of a small-sized linear electrodynamic actuator, to be inserted below a computer key so as to provide a force feedback to the user. The importance given to the sense of feeling has been growing in differen ...

Electron cyclotron emission spectrometry on the Tokamak a Configuration Variable

Ambrogio Fasoli, Timothy Goodman, Stefano Alberti, Patrick Blanchard, Laurie Porte, Igor Klimanov

Electron cyclotron emission (ECE) measurements are an important component of the diagnostic suite on the Tokamak a Configuration Variable (TCV) [F. Hoffman , Plasma Phys. Controlled Fusion 36, B277 (1994)]. A recently installed, 24-channel dual-conversion ...
