An Iterative Algorithm for Joint Signal and Interference Alignment
We consider the problem of signal design for transmission over an interference channel, along the lines of the recently proposed strategy of Interference Alignment. In the framework of interference alignment, each receiver maintains an interference subspac ...

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...
2010EQUALIZATION BY THE PULSE SHAPE INVERSE OF THE INPUT TO THE FRI PROCESSING IN PULSE BASED COMMUNICATIONS
Certain aspects of the present disclosure relate to a method for equalizing a pulse signal corrupted by a noise and by various channel effects for obtaining a signal based on the periodic-sinc pulse, which is suitable for Finite Rate of Innovation (FRI) pr ...
USPTO2010Caractérisation de la génération et la propagation d'ondes de pressions dans des tissus biologiques pour la conception d'appareils médicaux
Therapies using so called extracorporeal shock waves (Extracorporeal Shock Wave Therapy ESWT) have become current medical practice in orthopedy and traumatology. In order to understand and to optimize the effect of shock waves in clinical applications, med ...

The wideband RF receiver in a software-defined radio (SDR) system suffers from the nonlinear effects caused by the front-end analog processing. In the presence of strong blocker (interference) signals, such nonlinearities introduce severe cross modulation ...
2009General analytical model for distributed Brillouin sensors with sub-meter spatial resolution
A general analytic solution for Brillouin distributed fibre sensors with sub-meter spatial resolution has been obtained by solving the coupled wave equation by a perturbation method. The effect of the interaction of a square pump pulse with a continuous si ...
SPIE2009Line-of-sight data transmission system based on Mid IR quantum cascade laser - art. no. 68770F
Hubert van den Bergh, Valentin Simeonov
We report on an application of a pulsed distributed feedback quantum cascade laser (QCL) for an open path data transmission. A pulse QCL in the 1046 cm(-1) range (28.7 THz) is used as a carrier signal source. The QCL is modulated with 50 ns pulses at repet ...

Pierre Vandergheynst, Gianluca Monaci, Anna Llagostera Casanovas
In this work we present a method to jointly separate active audio and visual structures on a given mixture. Blind Audiovisual Source Separation is achieved exploiting the coherence between a video Signal and a one-microphone audio track. The efficient repr ...
