Ray-tracing evaluation of diffuse scattering in an outdoor scenario

This paper compares radio channel measurements and ray tracing simulations in an outdoor environment. A model for diffuse scattering is implemented in a ay tracing tool. Simulations results show that this implementation is important to improve both pathloss and crosspolarization accuracy prediction. To improve delay spread prediction it is necessary to increase the maximum number of simulated interactions that a ray can undergo, at cost of a considerable increase of computation time.
