Multipath propagation model of spatio-temporal dispersion observed at base station in urban areas

This paper presents a multipath propagation model for microcells in urban areas. The proposed model is a statistical geometric model that describes the propagation characteristics for propagation loss, power delay profiles, and power azimuth spectra. The applicable target of the proposed model is long-term characteristics such as the characteristics that depend on the height of a base station (BS) and the distance between the BS and a mobile station. Calculated power delay profiles and power azimuth spectra based on the model are similar to those of the power function. In order to verify the validity of the model, the power delay profiles and power azimuth spectra are measured. The measurement results agree well with the simulation results based on the model and the validity of the model is confirmed.
