3D urban propagation model for large ray-tracing computation

The paper presents a 3D urban propagation model that aims at providing fast 3D deterministic predictions in urban radio configurations and over large areas. The model addresses all types of outdoor transmitter configurations (macrocells, minicells, microcells and picocells) and all types of receiver locations (at ground level, over the rooftop and at high building floors). It predicts the field strength as well as the specular contributions of the impulse responses, which are essential in the performance estimate of new radio systems (diversity, MIMO).
