Abstract :
A second generation 3-D ray-tracing propagation model for microcell communication system design is presented which includes a treatment for scattering from complex surfaces and structures of real buildings. Scattering profiles from several rough surface building configurations are theoretically developed using ray-tracing methods. A simplified scattering function based on these profiles is presented and incorporated in the microcell ray-tracing model. Results of ray-tracing predictions which include the rough surface scattering function show better agreement with measurements than ray-tracing without the scattering function
