Modeling power angle spectrum and antenna pattern directions in multipath propagation environment

Abstract

Most propagation models do not consider the influence of antenna patterns on the parameters and characteristics of received signals. This assumption is equivalent to the use of isotropic or omnidirectional antennas in these models. Empirical measurement results indicate that the radiation pattern, gain and direction of directional antennas significantly influence on properties of the received signal. This fact shows that consideration the directional antennas in propagation models is very important especially in the context of emerging telecommunication technologies such as beamforming or massive MIMO. The purpose of this paper is to present the modeling method of power angular spectrum and direction of antenna patterns in a multipath propagation environment.Index Terms-multipath propagation, channel modeling, power angle sprectrum, power azimuth sprectrum, antenna pattern, directional antenna, multi-elliptical channel model, non-line-of-sight conditions.

Comparison of angular spread for 6 and 60 GHz based on 3GPP standard

“…In this case, the scatterers are located on multihalfelipsoid planes. An analogous method of modeling limited only to the azimuth plane is shown in [12]. This approach is used in this paper.…”

“…Input data for the multi-elliptical propagation model are: PDP/PDS, Tx-Rx distance, number of paths for each timecluster, parameters of the transmitting and receiving antennas, i.e., gain and half power beamwidth (HPBW) in the azimuth plane, for each antenna, respectively [12]. In addition, for the local scattering components, a parameter defining the von Mises distribution is specified.…”

“…As a result of the described algorithm, we obtain the sets of AOAs and powers. Based on these sets, PDF of AOA, f (φR), is estimated [12]. In this paper, the so-defined PDF of AOA are used to assess the angular dispersion of the received signals.…”

“…In these studies, the multi-elliptical propagation model is used. On the one hand, this model allows considering the patterns of the transmitting and receiving antennas [12]. On the other hand, it allows accurate mapping the measurement data [16].…”
