A Novel Approach to Over-Rooftop Multiple Diffractions by an Array of Buildings of Arbitrary Height and Spacing for Mobile Radio Wave Propagation

摘要

A new approach to obtain field at the receiver due to multiple over-rooftop diffraction by an array of buildings with irregular height and spacing is presented. In the literature, the available approach is based on ray-tracing method that requires higher order diffraction coefficient (slope diffraction). The proposed method is efficient in the sense that it does not require higher order diffraction term to compute field strength. The method is validated by comparing the predicted results with available measurements and earlier results from the literature.
