Abstract

In this paper, we evaluate the root mean square error (RMSE) performance of MUSIC ("Multiple Signal Classification") and COMET ("COvariance Matching EsTimator") algorithms in the presence of dispersion in azimuth and elevation. We use a 3D hemishperoid scattering model to describe angle of arrival in azimuth and elevation. We derive a closed- form expression for the joint and marginal probability density function (PDF) of the uplink angle of arrival (AOA) in azimuth and elevation. The base station is elevated to support the macrocellular model where the scatterers are distributed about the mobile (MS). We also compare the PDF of AOA and the simulated histogram.
