Estimation of Toeplitz Covariance Matrices in Large Dimensional Regime with Application to Source Detection
Julia Vinogradova, Romain Couillet, Walid Hachem
In this article, we derive concentration inequalities for the spectral norm of two classical sample estimators of large dimensional Toeplitz covariance matrices, demonstrating in p…
