Fast Ray Tracing for Microcellular and Indoor Environments

Arno Formella Universität des Saarlandes, FB 14 Informatik, 66041 Saarbrücken, Germany Abstract—We present a very efficient algorithm which calculates deterministically the path losses, delay profiles and other characteristics of a mobile channel. The algorithm can be used both for indoor and outdoor environments. We apply the technique of tracing rays and compute reflections, transmissions and diffractions with the help of geometrical optics, heuristical approximations and the uniform theory of diffraction (UTD).
