Abstract

In this paper we present analytical expressions for the angle-of-arrival (AOA) power density function (PDF) and its application in geometrically based channel models for urban environments. In order to evaluate the theoretical clusters PDF in angle domain proposed, we make computer simulations and comparisons with experimental results for wideband channel models, published in the open literature. The comparison with experimental results shows good agreement. The generalized clusters PDF derived in this paper can be used to simulate a power-delay-angle profile and to quantify second order statistics, i.e., angle spread for a given elliptical shape of the cluster
