Analysis of Sum-Weight-like algorithms for averaging in Wireless Sensor Networks
Franck Iutzeler, Philippe Ciblat, Walid Hachem
Distributed estimation of the average value over a Wireless Sensor Network has recently received a lot of attention. Most papers consider single variable sensors and communications…
A CLT on the SNR of Diagonally Loaded MVDR Filters
Francisco Rubio, Xavier Mestre, Walid Hachem
This paper studies the fluctuations of the signal-to-noise ratio (SNR) of minimum variance distorsionless response (MVDR) filters implementing diagonal loading in the estimation of…
The outliers among the singular values of large rectangular random matrices with additive fixed rank deformation
Francois Chapon, Romain Couillet, Walid Hachem +1
Consider the matrix where the matrix $X_n \in \C^{N\times n}$ has Gaussian standard independent elements, is a deterministic diagonal non…
Performance of a Distributed Stochastic Approximation Algorithm
Pascal Bianchi, Gersende Fort, Walid Hachem
In this paper, a distributed stochastic approximation algorithm is studied. Applications of such algorithms include decentralized estimation, optimization, control or computing. Th…
