A CLT for Information-theoretic statistics of Non-centered Gram random matrices

Walid Hachem, Malika Kharouf, Jamal Najim +1

In this article, we study the fluctuations of the random variable: $I_{n} (ρ) = \frac{1}{N} lo g det (Σ_{n} Σ_{n}^{*} + ρ I_{N}), (ρ > 0)$ where $Σ_n= n^{-1/2} D_n^{1/2} X_n\tild…

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 $K$ deterministic sources impinging on an array of $M$ antennas, from $N$ observations of the source s…
