Abstract
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.
