Terahertz Channel Modeling Based on Scattering Characterization

Terahertz (THz) communication is one of the key technologies of the sixth-generation mobile communication sys-tem (6G) and is receiving more and more attention for its large bandwidth and ultra-high data rate features. To support the performance evaluation of THz wireless communication devices, it is critical to model wireless channels that can characterize the channel properties. In this paper, a THz channel model is proposed based on the scattering characterization. The channel model is then applied to generate channel coefficients and power delay profiles (PDPs) in an indoor scenario. The evaluation results indicate that the proposed channel model can appropriately characterize THz scattering properties and support THz communication system design. Finally, we summarize the advantages of this model and point out the next research content.
