ANALYSIS AND SIMULATION OF THE DIFFUSE SCATTERING PHENOMENON IN URBAN ENVIRONMENT

Sophisticated measurement data, including path-loss, delay spread and direction-of-arrival, are analyzed and compared with simulations performed with an advanced 3D ray tracing model which takes diffuse scattering into account. The results show that diffuse scattering plays a key role in urban propagation, with a particular impact on the time delay- and on the angular- spread of the signal at the receiver. Since the great majority of mobile radio communications take place nowadays in urban environment, the study of urban radio propagation is of crucial importance for both the design and the deployment of present and future mobile radio systems. Urban propagation is a complex phenomenon which involves several mechanisms of interaction between th
