Random Linear Modulation with Spherically Symmetric Modulators

Armine Bagyan, Donald Richards

We consider the modulation of data given by random vectors $X_{n} \in R^{d_{n}}$ , $n \in N$ . For each $X_{n}$ , one chooses an independent modulating random vector $Î_n…

Complete Asymptotic Expansions for the Normalizing Constants of High-Dimensional Matrix Bingham and Matrix Langevin Distributions

Armine Bagyan, Donald Richards

For positive integers $d$ and $p$ such that $d \geq p$ , let $R^{d \times p}$ denote the set of $d \times p$ real matrices, $I_{p}$ be the identity matrix of order $p$ , and $V…
