Abstract

A UTD-based technique for solving multiple diffraction problems of buildings in mobile cellular situations is derived. For microwave propagation over building rooftop or along building surface at grazing incidence, the slope diffraction term plays an important role in calculating the double-edge diffraction coefficient and should be combined with the modified multiplication factor further. Good agreements indicate that this prediction model may be a helpful tool for cellular mobile system planning
