Detailed characterization of radio propagation channel is a major requirement for successful design of mobile communication systems. In this paper, mobile radio channel characterization process based on the FDTD method is presented. The merits and demerits of the currently used methods, namely impulse-response method and ray-tracing methods are briefly considered, and the total field formulation of the FDTD method is discussed. The simulation model consists of streets with concrete buildings. The wave propagation patterns in the whole channel and the received signals at some line of sight and out of sight locations are presented.
