摘要

本文分析了两个独立复高斯矢量之间的相位角分布的von Mises近似。通过Kullback-Leibler散度的上界，表明当它们的圆形均值和方差重合时，分布在低信噪比和高信噪比情况下都收敛于von Mises分布。

On the von mises approximation for the distribution of the phase angle between two independent complex Gaussian vectors

This paper analyses the von Mises approximation for the distribution of the phase angle between two independent complex Gaussian vectors. By upper bounding the Kullback-Leibler divergence, it is shown that when their circular means and variances coincide, the distribution converges to a von Mises distribution both in the low and high signal-to-noise ratio regimes.
