Channel Sounding and Ray Tracing for THz Channel Characterization

In order to effectively support the design and evaluation of future teraheartz (THz) communications, the fundamental knowledge of the propagation channel characteristics is of paramount significance. In this paper, we introduce a channel characterization method based on ultra-wideband (UWB) channel sounding and ray tracing (RT). As a case study, the channel in intra-wagon scenario at 300 GHz band is characterized through extensive simulations using an RT simulator which is validated by the channel sounding results.
