Multiplexing schemes for optical communication through atmospheric turbulence
Liliana Borcea, Josselin Garnier, Knut Solna
A central question in free-space optical communications is how to improve the transfer of information between a transmitter and receiver. The capacity of the communication channel…
High-Resolution Interferometric Synthetic Aperture Imaging in scattering media
Liliana Borcea, Josselin Garnier
The goal of synthetic aperture imaging is to estimate the reflectivity of a remote region of interest by processing data gathered with a moving sensor which emits periodically a si…
Intensity fluctuations in random waveguides
Josselin Garnier
An asymptotic analysis of wave propagation in randomly perturbed waveguides is carried out in order to identify the effective Markovian dynamics of the guided mode powers. The main…
A control variate method driven by diffusion approximation
Josselin Garnier, Laurent Mertz
In this paper we examine a control variate estimator for a quantity that can be expressed as the expectation of a functional of a random process, that is itself the solution of a d…
Application of the interacting particle system method to piecewise deterministic Markov processes used in reliability
H. Chraibi, A. Dutfoy, T. Galtier +1
Variance reduction methods are often needed for the reliability assessment of complex industrial systems, we focus on one variance reduction method in a given context, that is the…
How a moving passive observer can perceive its environment ? The Unruh effect revisited
Mathias Fink, Josselin Garnier
We consider a point-like observer that moves in a medium illuminated by noise sources with Lorentz-invariant spectrum. We show that the autocorrelation function of the signal recor…
