Uniform Analysis of Multipath Components from Various Scenarios with Time-Domain Channel Sounding at 300GHz

Knowledge of the wireless channel remains crucial for the development of applications such as joint communication and sensing, intelligent reflective surfaces or terahertz communications that are currently discussed as fundamental part of the sixth generation of mobile systems. To benefit from synergies, a uniform and collaborative data evaluation of measurement sets from two different time-domain channel sounders is presented in this paper. Based on a common signal processing that extracts discrete multipath components, the properties of the propagation channel are analyzed. The channels show a great variety of characteristics depending on the scenario, the line-of-sight condition and the signal-to-noise ratio requirements of the prospective communication system. Considering the impact of a realistic antenna array, the radio channel that is ultimately relevant for the communication system is examined. Having less impact due to the spatial filtering, the different characteristics of multipath propagation still emphasize the brought range of terahertz channels. The extracted multipath components are published as research data to serve the community for future analytical studies and simulations in relevant scenarios for the sixth generation of mobile systems.
