摘要：

In this paper, an efficient time-domain ray model is developed for ultra wideband (UWB) indoor multipath propagation channel. This model is based on time-domain uniform geometrical theory of diffraction (TD-UTD) technique, which consists of three basic ray mechanisms of geometrical optics (GO) and UTD, i.e., directed ray, multi-reflected rays from lossy surfaces, and diffracted ray from lossy edge. The useful approximated analyses of TD multi-reflected rays with horizontal polarization and vertical polarization are provided. The TD diffraction coefficient is described. A software-based TD ray tracing tool has been developed to determine all paths of multiple reflections and diffractions, propagation delay of each path, pulse waveform and amplitude, and TD path loss. The simulation results in a typical office room are presented.
