Large information plus noise random matrix models and consistent subspace estimation in large sensor networks
Walid Hachem, Philippe Loubaton, Xavier Mestre +2
In array processing, a common problem is to estimate the angles of arrival of deterministic sources impinging on an array of antennas, from observations of the source s…
A Subspace Estimator for Fixed Rank Perturbations of Large Random Matrices
Walid Hachem, Philippe Loubaton, X. Mestre +2
This paper deals with the problem of parameter estimation based on certain eigenspaces of the empirical covariance matrix of an observed multidimensional time series, in the case w…
Almost sure localization of the eigenvalues in a gaussian information plus noise model. Applications to the spiked models
Philippe Loubaton, Pascal Vallet
Let be a random matrix defined by where is a uniformly bounded deterministic matrix and…
On bilinear forms based on the resolvent of large random matrices
Walid Hachem, Philippe Loubaton, Jamal Najim +1
Consider a matrix with random independent entries, each non-centered with a separable variance profile. In this article, we study the limiting behavior of the random bilinear…
