Abstract

Ray-tracing propagation model (RTPM) has been widely used for predicting channel characteristics, whereas the scenarios considered are generally static. The complexity of RTPM is significantly increased due to the rapidly time-varying scenario resulted from moving scatterers. A three-dimensional (3D) dynamic RTPM considering moving scatterer effects is advanced in this paper. First, a simplified dynamic scenario preprocessing method based on the predefined active region and face transformation is proposed. The random movement of multiple scatterers can be enabled without repeated scenario modeling. Second, an efficient dynamic ray-tracing method based on self-adaptive ray-launching technique is advanced. The computational efficiency of the dynamic RTPM can be significantly improved due to the exclusion of repeated ray-tracing process over time. Finally, the feasibility and accuracy of the RTPM is verified by comparing the simulation results with the measurements performed in an indoor scenario with pedestrians.
