A New Approach for Capacity Analysis of Large Dimensional Multi-Antenna Channels
Walid Hachem, Oleksiy Khorunzhiy, Philippe Loubaton +2
This paper adresses the behaviour of the mutual information of correlated MIMO Rayleigh channels when the numbers of transmit and receive antennas converge to infinity at the same…
Homodyne detection for quantum key distribution: an alternative to photon counting in BB84 protocol
M. B. Costa e Silva, Q. Xu, S. Agnolini +2
This paper presents the principles and experimental results of an optical fiber QKD system operating at 1550 nm, and using the BB84 protocol with QPSK signals. Our experimental set…
On the existence of some ARCH() processes
Randal Douc, François Roueff, Philippe Soulier
A new sufficient condition for the existence of a stationary causal solution of an ARCH() equation is provided. This condition allows to consider polynomially decaying coef…
Ranking the best instances
Stéphan Clémençon, Nicolas Vayatis
We formulate the local ranking problem in the framework of bipartite ranking where the goal is to focus on the best instances. We propose a methodology based on the construction of…
Sequential Monte Carlo smoothing with application to parameter estimation in non-linear state space models
Jimmy Olsson, Olivier Cappé, Randal Douc +1
This paper concerns the use of sequential Monte Carlo methods (SMC) for smoothing in general state space models. A well-known problem when applying the standard SMC technique in th…
A functional central limit theorem for the M/GI/ queue
Laurent Decreusefond, Pascal Moyal
In this paper, we present a functional fluid limit theorem and a functional central limit theorem for a queue with an infinity of servers M/GI/. The system is represented b…
