Abstract

In this paper we investigate the angular properties of the Dense Multipath Components (DMC) using realistic measurement data. We introduce a Gauss-Newton (GN) based algorithm to jointly estimate the parameters of the angular model that is comprised of a Von-Mises-Distribution (VMD) and an additional Uniform-Distribution (UD). We observe that the power of the DMC is in the average only one tenth of the power of the resolvable specular paths. Furthermore, we show that the DMC appear to be uniformly distributed in the angular domain in a lot of cases. This is mainly caused by a limite dynamic range of the data preventing a proper estimation of the VMD.
