论文摘要
Terahertz（THZ）通信（THZCOM）由于其对第六代（6G）和ERA以后的超高数据速率传输的好处而引起了人们的兴趣增长。尽管如此，关于探索THZCOM对6G预期的其他性能目标的潜力的研究，包括大规模连通性和安全性，仍处于起步阶段。在本文中，我们首先简要描述THZ渠道的独特特点，然后讨论理论框架，以促进THZ传输的分析和设计，以实现巨大的连接性和安全性。然后，我们讨论有希望的频谱管理策略，包括探索多个THZ传输窗口和使用多重和信号处理的频率重复使用，以实质上增加了支持用户的数量并确定挑战的挑战。我们进一步提出了基于物理层安全性原理的重要研究方向，例如新的频谱分配策略和波束形成算法，以与窃听的THZCOM系统进行战斗，并使用安全的THZCOM系统。
Terahertz (THz) communications (THzCom) has experienced a meteoric rise of interest, due to its benefits for ultra-high data rate transmission in the sixth generation (6G) and beyond era. Despite so, the research on exploring the potential of THzCom for other performance targets anticipated by 6G, including massive connectivity and security, is still in its infancy. In this article, we start with briefly describing the unique peculiarities of THz channels, and then discuss theoretical frameworks to facilitate the analysis and design of THz transmission for achieving massive connectivity and security. Then we discuss promising spectrum management strategies, including the exploration of multiple THz transmission windows and frequency reuse with multiplexing and signal processing, to substantially increase the number of supported users and identify to-be-tackled challenges. We further present important research directions based on the principles of physical layer security, such as new spectrum allocation policies and beamforming algorithms, to fight against eavesdropping in THzCom systems, ushering in secure THzCom systems.
