Approximate Ergodic Capacity of a Class of Fading 2x2x2 Networks

Michael Christoph Gastpar, Chien-Yi Wang

We study a 2-user 2-hop network with 2 relays in which channel coefficients are independently drawn from continuous distributions and vary over time. For a broad class of channel distributions, we characterize the ergodic sum capacity within a constant num ...

La détection de périodicités cachées

Jean-Marc Nicoletti

This thesis is a small part of the preparation of the launch of the Gaia mission, a satellite of the European Space Agency (ESA). One of the goals of the mission is to perform a classification among variable stars considering different attributes. Periodic ...

Approximate Ergodic Capacity of a Class of Fading 2-user 2-hop Networks

Michael Christoph Gastpar, Chien-Yi Wang

We consider a fading AWGN 2-user 2-hop network in which the channel coefficients are independently and identically distributed (i.i.d.) drawn from a continuous distribution and vary over time. For a broad class of channel distributions, we characterize the ...

Modelling wind-driven rain on buildings in urbanized area using 3-D GIS and LiDAR datasets

Luca Rossi, François Golay, Sylvain Coutu, Claudio Magalhaes Carneiro, Pauline Emery, Vera Wyrsch

This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implemen ...

Learning with Compressible Priors

Volkan Cevher

We describe a set of probability distributions, dubbed compressible priors, whose independent and identically distributed (iid) realizations result in p-compressible signals. A signal x in R^N is called p-compressible with magnitude R if its sorted coeffic ...

Hitting time of large subsets of the hypercube

Jiri Cerny, Véronique Gayrard

We study the simple random walk on the n-dimensional hypercube, in particular its hitting times of large (possibly random) sets. We give simple conditions on these sets ensuring that the properly rescaled hitting time is asymptotically exponentially distri ...

Sufficient-Statistics Based Multiple Access over Wireless Fading Channels

Michael Christoph Gastpar

In this work, we study a communication scheme in which nodes transmit sufficient statistics of their observations over non-orthogonal medium access channels for distributed estimation. This scheme unifies and generalizes several multiple access schemes suc ...

Signatures of vegetational functional diversity in river basins

Andrea Rinaldo

Using radiative reflectance as the discriminatory functional trait, we find scale-free signatures of local functional diversity density of vegetation in river basins, implying a high likelihood of locations with very high diversity relative to the overall ...

A delay optimal policy for symmetric broadcast channels

Stéphane Musy

We consider the rate allocation problem when two users (each one associated with one receiver) send packets through a symmetric broadcast channel. Under the assumption that the packet lengths are exponentially distributed, we establish the delay optimality ...

Self-similar density turbulence in the TCV tokamak scrape-off layer

Jonathan Graves, Richard Pitts, Jan Horacek

Plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak exhibit statistical properties which are universal across a broad range of discharge conditions. Electron density fluctuations, from just inside the magnetic separatrix to the plasma-wall ...
