论文摘要
Terahertz（0.1-10 THZ）带具有巨大的潜力，可借助其超大的带宽来支撑前所未有的数据速率和毫米级的准确感测。 Terahertz集成的传感和通信（ISAC）被视为一种改变游戏规则的技术，可以实现6G和超越系统中的连接智能。在本文中，阐述了THZ渠道和收发器的角度以及ISAC困难的挑战。受这些挑战的激励，根据渠道类型，测量和模型，研究了THZ ISAC渠道。此外，研究了四种关键信号处理技术，以释放THZ ISAC的全部潜力，即波形设计，接收器处理，窄梁管理和本地化。定量研究证明了最先进的信号处理方法的益处和性能。最后，讨论了开放问题和潜在解决方案。
The Terahertz (0.1-10 THz) band holds enormous potential for supporting unprecedented data rates and millimeter-level accurate sensing thanks to its ultra-broad bandwidth. Terahertz integrated sensing and communication (ISAC) is viewed as a game-changing technology to realize connected intelligence in 6G and beyond systems. In this article, challenges from THz channel and transceiver perspectives, as well as difficulties of ISAC are elaborated. Motivated by these challenges, THz ISAC channels are studied in terms of channel types, measurement and models. Moreover, four key signal processing techniques to unleash the full potential of THz ISAC are investigated, namely, waveform design, receiver processing, narrowbeam management, and localization. Quantitative studies demonstrate the benefits and performance of the state-of-the-art signal processing methods. Finally, open problems and potential solutions are discussed.
