  • Tài hè zī diàn bō chuán bō jí xìn dào tè xìng [Elektronski vir] = Terahertz wave propagation and channel characterization
    Yi, Haofan ...
    Firstly, the different characteristics of terahertz waves compared to lower frequency bands were summarized, including the influence of meteorological factors and rough surfaces of materials on THz ... waves. Next, it was proposed to use ray-tracing (RT) technology to calibrate the three-dimensional (3D) environment model and electromagnetic parameters of materials in the target scenarios through very limited channel measurement data. Then, the reversed parameters were utilized to perform in a similar but more general scenario, instead of a large amount of channel measurement data. Finally, the channel characteristics were analyzed by extraction of the channel key parameters, such as path loss, shadow fading, Rician K-factor, delay spread, angular spread, and doppler parameters in a mobile scenario. Representing two ends of 6G THz use cases from indoor scenario to outdoor scenario, case studies were made for wireless connections on a desktop and vehicular communications, respectively. As for the outdoor scenario, the influences of meteorological factors were additionally considered. The work is of great significance for the design and evaluation of the THz communication system.
