论文摘要
借助丰富的带宽资源，Terahertz频段（0.1〜THz至10〜THz）被视为一种关键技术，以实现6G和移动通信系统以外的超高数据速率。但是，搬到THZ频段时，专门用于微波炉或毫米波频段的现有通道模型无效。为了填补这一研究差距，需要进行广泛的渠道测量活动和特征。在本文中，使用基于频率域的矢量网络分析仪（VNA）的声音，在306-321 GHz频段的建筑物室外中庭进行了测量活动。进一步处理测量的数据以获得通道传输函数（CTF），多径成分（MPC）的参数以及聚类结果。基于MPC参数，计算和分析了通道特征，例如路径损失，阴影褪色，K因子等。提取的通道特征和命理学有助于研究THZ通信的渠道建模和指导系统设计。
With abundant bandwidth resource, the Terahertz band (0.1~THz to 10~THz) is envisioned as a key technology to realize ultra-high data rates in the 6G and beyond mobile communication systems. However, moving to the THz band, existing channel models dedicated for microwave or millimeter-wave bands are ineffective. To fill this research gap, extensive channel measurement campaigns and characterizations are necessary. In this paper, using a frequency-domain Vector Network Analyzer (VNA)-based sounder, a measurement campaign is conducted in the outdoor atrium of a building in 306-321 GHz band. The measured data are further processed to obtain the channel transfer functions (CTFs), parameters of multipath components (MPCs), as well as clustering results. Based on the MPC parameters, the channel characteristics, such as path loss, shadow fading, K-factor, etc., are calculated and analyzed. The extracted channel characteristics and numerology are helpful to study channel modeling and guide system design for THz communications.
