Iterative Deterministic Equivalents for the Performance Analysis of Communication Systems
Jakob Hoydis, Romain Couillet, Merouane Debbah
In this article, we introduce iterative deterministic equivalents as a novel technique for the performance analysis of communication systems whose channels are modeled by complex c…
Fluctuations of spiked random matrix models and failure diagnosis in sensor networks
Romain Couillet, Walid Hachem
In this article, the joint fluctuations of the extreme eigenvalues and eigenvectors of a large dimensional sample covariance matrix are analyzed when the associated population cova…
Asymptotic Analysis of Double-Scattering Channels
Jakob Hoydis, Romain Couillet, Merouane Debbah
We consider a multiple-input multiple-output (MIMO) multiple access channel (MAC), where the channel between each transmitter and the receiver is modeled by the doubly-scattering c…
Random Beamforming over Correlated Fading Channels
Jakob Hoydis, Romain Couillet, Merouane Debbah
We study a multiple-input multiple-output (MIMO) multiple access channel (MAC) from several multi-antenna transmitters to a multi-antenna receiver. The fading channels between the…
Signal Processing in Large Systems: a New Paradigm
Romain Couillet, Merouane Debbah
For a long time, detection and parameter estimation methods for signal processing have relied on asymptotic statistics as the number of observations of a population grows large…
