Universality for the largest eigenvalue of sample covariance matrices with general population

This paper is aimed at deriving the universality of the largest eigenvalue of a class of high-dimensional real or complex sample covariance matrices of the form WN = Σ 1 /2 XX* Σ 1/2. Here, X = (xij)M,N is an M x N random matrix with independent entries xij, 1 ≤ i ≤ M, 1 ≤ j ≤ N such that Exij = 0,...
