摘要:

太赫兹(0.1-10 THz)通信被设想为第六代(6 G)无线系统的关键技术。太赫兹无线传输信道的研究为发展可靠的太赫兹通信系统及其应用提供了基础。本文对太赫兹无线信道的研究进行了全面的综述。首先介绍了目前最流行的三种THz信道测量方法,即基于矢量网络分析仪(VNA)的频域信道测量方法、基于滑动相关的时域信道测量方法和基于时域光谱技术的THz脉冲时域信道测量方法,并对这三种方法进行了比较。当前的渠道测量系统和测量活动进行了审查。然后,现有的信道建模方法分为确定性,随机和混合方法。分析了当前THz信道模型的发展现状,介绍了基于THz信道模型的信道模拟器。接下来,在太赫兹波段的通道特性的深入审查。最后,阐述了6 G太赫兹无线信道研究中存在的问题和未来的研究方向。

英文摘要:

Terahertz (0.1-10 THz) communications are envisioned as a key technology for sixth generation (6G) wireless systems. The study of underlying THz wireless propagation channels provides the foundations for the development of reliable THz communication systems and their applications. This article provides a comprehensive overview of the study of THz wireless channels. First, the three most popular THz channel measurement methodologies, namely, frequency-domain channel measurement based on a vector network analyzer (VNA), time-domain channel measurement based on sliding correlation, and time-domain channel measurement based on THz pulses from time-domain spectroscopy (THz-TDS), are introduced and compared. Current channel measurement systems and measurement campaigns are reviewed. Then, existing channel modeling methodologies are categorized into deterministic, stochastic, and hybrid approaches. State-of-the-art THz channel models are analyzed, and the channel simulators that are based on them are introduced. Next, an in-depth review of channel characteristics in the THz band is presented. Finally, open problems and future research directions for research studies on THz wireless channels for 6G are elaborated.
