Abstract

6G wireless communication technology is expected to provide a higher peak data rate, lower latency, high mobile speed, high spectral efficiency, and high network energy efficiency in the future. It has the advantages of wide coverage, high security, and low-cost efficiency. As one of the candidate frequency bands of 6G technology, THz wave (0.1-10 THz) bridges the infrared band and the microwave band and has a very important application prospect in the communication process. Due to the terahertz source power and the absorption of various particles in the air, indoor short-range terahertz wireless communication has practical research value. In this paper, for the three-dimensional scene of common indoor conference rooms, the ray tracing method is used to model the terahertz channel of the line-of-sight (LOS) path, the primary reflection path, and the secondary reflection path. The carrier frequency range used for the simulation is 220-330 GHz. By calculating the power loss and required time of each path from the transmitter to the receiver, parameters such as the power delay profile are obtained. Then, the related terahertz channel parameters such as Rician K-factor and root mean square (RMS) delay spread are analyzed.
