Propagation model based on ray tracing for the design of personal communication systems in indoor environments

Abstract—In this paper, a ray-tracing technique to predict the propagation channel parameters in indoor scenarios is presented. It is a deterministic technique, fully three-dimensional, based on geometrical optics (GO) and the uniform theory of diffraction (UTD). A model of plane facets is used for the geometrical description of the environment. The ray tracing is accelerated considerably by using the Angular Z-Buffer algorithm. Some comparisons between predicted results and measurements are presented to validate the method. I
