摘要：
A novel method for microcellular communications to predict propagation characteristics is presented in this paper, It takes into account multiple reflections among walls, ground, vehicles, as well as the transmission/reflection due to groups of trees, Although these are three-dimensional (3-D) problems, we can combine two dimensional (2-D) ray tracing and simple 3-D geometric considerations to solve them in a very efficient way. We have investigated the propagation loss versus size, number, and locations of vehicles and groups of trees on a safe island, our results show that the radio wave propagation exhibits severe fast fading, attenuation, and blockage due to reflection, transmission, and shadowing, respectively.
