相关复随机Wishart矩阵的特征值密度

Eigenvalue Density of Correlated Complex Random Wishart Matrices

Steven H. Simon, Aris L. Moustakas

摘要:

本文利用特征展开法精确计算了M^ \dagger M型随机矩阵的特征值密度,其中M是由归一化分布P(M)~ exp(- \Tr(A M B M^ \dagger))中抽取的复矩阵,具有任意维数的A和B正定(方阵)。这种所谓的“相关Wishart矩阵”出现在从信息论到多变量分析的许多领域。

英文摘要:

Using a character expansion method, we calculate exactly the eigenvalue density of random matrices of the form M^\dagger M where M is a complex matrix drawn from a normalized distribution P(M) ~ exp(-\Tr(A M B M^\dagger) with A and B positive definite (square) matrices of arbitrary dimensions. Such so-called ``correlated Wishart matrices'' occur in many fields ranging from information theory to multivariate analysis.
