The Eigenvectors of Single-spiked Complex Wishart Matrices: Finite and Asymptotic Analyses

Prathapasinghe Dharmawansa, Pasan Dissanayake, Yang Chen

Let $W \in C^{n \times n}$ be a {\it single-spiked} Wishart matrix in the class $W \sim C W_{n} (m, I_{n} + θ v v^{†})$ with…

Distribution of the Scaled Condition Number of Single-spiked Complex Wishart Matrices

Pasan Dissanayake, Prathapasinghe Dharmawansa, Yang Chen

Let $X \in C^{n \times m}$ ( $m \geq n$ ) be a random matrix with independent columns each distributed as complex multivariate Gaussian with zero mean and {\it single-s…
