Abstract

In this paper, the behaviors of small-scale flatness fading and fast fading with Doppler spectrum characteristics of outdoor wireless channel are studied using FDTD method. After the color-Gaussian stochastic process with Doppler spectrum that is necessary to the investigation of time-varied wireless channel statistical characteristics having been generated with Monte Carlo method, its far field stochastic signal is obtained by using FDTD method. Then, the Clarke and Suzuki models are reviewed, and the model of time-variant wireless channel based on its statistical fading behavior is presented. At last, the comparison between the stochastic distribution obtained with this method and the theoretic distribution is given. The validation of this method is verified.
