摘要

太赫兹频段（0.1~10 THz）信号在空气中传播衰减大、传输距离短，在太赫兹通信技术得到广泛应用之前，这些关键问题需要攻克。首先，介绍了当前太赫兹信道的研究进展，包括信道建模、信道测量及信道估计。在此基础上，分析了单用户基本通信场景和多用户复杂通信场景，并针对各个场景中存在的问题列举了可能的解决方案。最后，展望了太赫兹通信未来可行的研究方向。

Abstract

There are some challenges that need to be overcome before terahertz communication technology is widely applied

such as large propagation attenuation in the air and short transmission distance.Research progresses of terahertz channel

such as terahertz channel model

terahertz channel measurement and terahertz channel estimation

were first reviewed.Based on these characteristics of terahertz channel

the underlying problems in basic single-user communication scenarios and more complicated multi-user communication scenarios were respectively analyzed.For each scenario possible solutions were concluded.Last but not least

some prospect future research directions on terahertz communications were discussed.
