Reconfigurable Antennas for Beam-Space MIMO Transmission with a Single Radio
MIMO techniques allow remarkable improvements in the reliability and/or transmission rate of wireless communication systems. However, there are several major challenges towards the implementation of conventional MIMO concept in terminals with size, cost, a ...
EPFL2015A Low-Power PPM Demodulator for Remotely Powered Batteryless Implantable Devices
Catherine Dehollain, Enver Gürhan Kilinç, Franco Maloberti
A low-power PPM demodulator has been developed for remotely powered batteryless implantable devices. The required power is harvested by the magnetic coupling with external powering coils placed under the living space of the animal. The remote powering is t ...
Ieee2014A simple relaying strategy for diamond networks
Christina Fragouli, Siddhartha Brahma
We consider a Gaussian diamond network where a source communicates with the destination through n non-interfering half-duplex relays. Using simple approximations to the capacity of the network, we show that simple relaying strategies involving two relays a ...
Ieee2014ECMA-407: A New 3D audio codec implementation up to NHK 22.2
Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad
ECMA-407, the first 3D audio standard worldwide, introduces a new concept of static models to lower bitrate coding, which may be equally applied with channels, channels and objects and Higher Order Ambisonics (HOA). Static models may either operate in time ...
2014Switched Local Schedules for Diamond Networks
Christina Fragouli, Siddhartha Brahma, Ayan Sengupta
We consider a Gaussian diamond network where a source communicates with the destination through non-interfering half-duplex relays. We focus on half-duplex schedules that utilize only local channel state information, i.e., each relay has access to its ...
2014Objective Speech Intelligibility Assessment through Comparison of Phoneme Class Conditional Probability Sequences
Hervé Bourlard, Raphaël Marc Ullmann
Assessment of speech intelligibility is important for the development of speech systems, such as telephony systems and text-to-speech (TTS) systems. Existing approaches to the automatic assessment of intelligibility in telephony typically compare a referen ...
Idiap2014Flexible triangular formation keeping of marine robotic vehicles using range measurements.
Colin Neil Jones, Jorge Miguel Dias Almeida Rodrigues Soares, Francisco Fernandes Castro Rego
This paper addresses the problem of keeping an autonomous marine vehicle in a moving triangular formation by regulating its position with respect to two leader vehicles. The follower vehicle has no prior knowledge of the path described by the leaders but h ...
2014Forge: Generating a High Performance DSL Implementation from a Declarative Specification
Domain-specific languages provide a promising path to automatically compile high-level code to parallel, heterogeneous, and distributed hardware. However, in practice high performance DSLs still require considerable software expertise to develop and force ...
Assoc Computing Machinery2014Wireless Data and Power Transmission Aiming Intracranial Epilepsy Monitoring
Catherine Dehollain, Gürkan Yilmaz, Oguz Atasoy
This study presents a wireless power and data transmission system to overcome the problems in intracranial epilepsy monitoring associated with transcutaneous wires. Firstly, a wireless power transfer link based on inductive coupling is implemented and a po ...
Spie-Int Soc Optical Engineering2013Generalized Codes on Graphs and Applications in Content Distribution
The contribution of this thesis is twofold. In the first part, we generalize and analyze two classes of error correcting codes: LDPC codes and product codes. We generalize graphical codes by considering checks being arbitrary codes instead of single pariti ...
