Abstract :
The paper presents a model for the fast fading first and second-order statistics (amplitude distribution, level crossing rate and average duration of fades) of the received signal in millimeter communications in an urban environment. The model starts from physical considerations to infer the form of the functions representing the desired statistics. Their complete description requires the evaluation of a small number of parameters. Again from physical considerations it is determined how these parameters are related to the geometry of the operating environment in such a way that they can, for example, be computed with the help of computer graphics techniques. The model is then applied to the case of a long street, for which analytical results can be easily obtained. The results obtained from the model are compared with results obtained by simulation via ray tracing
