Summary: | A new propagation prediction model, suitable for an antenna placed below rooftop level in an urban environment is presented. It is shown that the contribution of various arriving rays at a specific location can be well approximated by a set of geometric progressions. Each progression is associated with a source. Then, estimation is delivered as soon as the leading term and the ratio have been computed. The ratio reflects the significance of secondary ray-paths. It depends on the geometry and the electromagnetic properties of the materials within the "street canyon." In contrast to typical semi-deterministic approaches, detailed information on the power, the time of arrival and the angle of arrival of all significant components is delivered. Consequently, wideband characterization of the environment is accomplished at short running-time. High accuracy is experimentally verified in a typical urban configuration |
