摘要

首先，综述太赫兹电波相较于低频电波传播的不同特性，包括气象因素和材料粗糙表面对电磁波的影响。接着，提出利用射线跟踪技术仅通过有限的信道测量数据校准目标场景中的三维环境模型以及材料电磁参数；然后，利用从射线跟踪仿真反演出的参数在类似场景中进行大量仿真，代替信道测量生成大量真实有效的全维度信道数据；最后，提取并分析信道特性，例如路径损耗、阴影衰落、莱斯K因子、均方根时延扩展、角度扩展及多普勒参数。2 个案例研究是从室内桌面通信到室外智能车联网场景，分别代表了 6G 移动通信从近到远用例的两端，对于室外场景还额外考虑了不同气象条件下对信道参数的影响，对太赫兹系统的设计和评估具有重大意义。

Abstract

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.
