Coverage Mapping with UTD Model

pdf PDF


Coverage prediction is vital for reliable digital communication and broadcasting systems. In order to increase QoS of these systems, the threshold field strength has to be provided and coverage map extracted before installation. In urban areas, direct fields are not allowed to reach the receiver point due to diffraction from high buildings. To calculate diffracted fields Uniform Theory of diffraction (UTD) model is proposed and this model is used to extract the coverage map. In this study, a scenario including 441 buildings is generated randomly and electric field is calculated at the top of all buildings. Finally, according to these electric fields coverage map is generated.
