Abstract:

The use of a spatial selection of radio links in 5G networks is conditioned by the assessment of a power angular spectrum (PAS) of received signals. In this paper, we present a simulation procedure that allows the determination of the PAS for various environmental conditions and antenna patterns. The simulation procedure is based on a propagation model, whose geometrical structure is a set of semi-ellipsoids. Statistical properties of the received signals and radiation power patterns of the antennas are used to generate parameters of propagation paths, i.e., radiation angles, power levels. The normalization of the antenna pattern is the basis for defining the radiation probability density function, which allows the generation of the propagation path directions. Exemplary results of simulation studies illustrate the PASs for various models of the antenna patterns and propagation conditions. The obtained results show that the use of statistical properties of the signals and antenna power radiation patterns in the simulation procedure allows mapping the influence of the propagation environment on the PAS.
