Abstract :
A novel statistical method for field prediction in an urban environment is presented. The method is based on a sort of "statistical ray tracing", that is, the main parameters of the generic ray (orientation, number of reflections, path length etc.) are evaluated through their statistical distribution on the basis of the characteristics of the environment. These characteristics can be extracted from a sample map by means of an automatic graphical algorithm
