Abstract

In this work we continue the analysis of a probabilistic approach and the corresponding stochastic multiparametric model of wave propagation in built-up areas with randomly distributed buildings. We concentrate on the influence of buildings´ overlay profile on signal decay within the UHF/X-band urban propagation channels. Using different buildings´ overlay profiles, the field loss characteristics are examined taking into account single scattering and multiple scattering phenomena, and diffraction from buildings´ comers and rooftops, for various positions of receiver and transmitter antenna with respect to surrounding obstacles. The comparison between experimental and theoretical predictions is presented.
