Abstract

Recently, research on 6G wireless communication technology has become a hot topic. In 6G technology, terahertz communication is considered the most promising part. The research and application of the terahertz communication frequency range (0.1-10 THz) will bring revolutionary changes to the field of communication. It has the potential to bridge the transmission gap between the infrared and microwave bands, and offers highspeed data transmission, low latency, and high-capacity communication. Therefore, the development of terahertz communication is highly anticipated as a significant driving force for 6G technology. At present, research on outdoor terahertz channels is far less extensive compared to indoor channels, requiring more efforts to explore the characteristics of outdoor terahertz channels. In this paper, we focus on the three-dimensional scenario of street canyon and model the terahertz channel using ray tracing. The carrier frequencies used for simulation range from 220 to 330 GHz. By calculating the power loss and required time for each path from the transmitter to the receiver, we obtain parameters such as power delay spectrum and power angle spectrum. Next, we analyze the relationships between path loss, delay spread, angle spread, and distance, gaining further understanding of the outdoor terahertz multipath channel characteristics.
