Inhalt:
In this paper, a novel three dimensional (3D) hybrid ray tracing (HRT) method for wave propagation simulation for large indoor and small cell urban environment is proposed. HRT combines two image based ray tracing (RT) methods: “standard” ray tracing (i.e., the rigorous and conventional image ray tracing) with high accuracy and “intelligent” ray tracing (i.e., visibility tree based image ray tracing) with less time consuming. To establish the accuracy of HRT, its simulation results were compared with millimeter wave (mmWave) measurements in a large indoor scenario under different visibility conditions. It shows that good predictions can be provided by HRT in many aspects, such as path loss, temporal characteristics, evolution of channel, etc. Meanwhile, mismatche and difference between measurement and simulation will be shown and be analyzed as well.
