摘要:

太赫兹(THz)波段通信是下一代无线通信系统的关键推动因素,该系统有望集成广泛的数据需求应用。光子、电子和等离子体技术的最新进展正在缩小THz收发器设计的差距。因此,前景太赫兹信号的产生,调制和辐射的方法正在收敛,相应的信道模型,噪声和硬件损伤的概念正在出现。这些进展为无线通信中的太赫兹信号处理技术的研究奠定了基础。本教程概述了这些技术,重点是超大规模多输入多输出(UM-MIMO)系统和可重构智能表面,这对于克服非常高频率下的距离问题至关重要。我们重点讨论了波形设计和调制、波束形成和预编码、索引调制、信道估计、信道编码和数据检测等经典问题。我们还激励信号处理技术的太赫兹传感和定位。

英文摘要:

Terahertz (THz)-band communications are a key enabler for future-generation wireless communications systems that promise to integrate a wide range of data-demanding applications. Recent advances in photonic, electronic, and plasmonic technologies are closing the gap in THz transceiver design. Consequently, prospect THz signal generation, modulation, and radiation methods are converging, and corresponding channel model, noise, and hardware-impairment notions are emerging. Such progress establishes a foundation for well-grounded research into THz-specific signal processing techniques for wireless communications. This tutorial overviews these techniques, emphasizing ultra-massive multiple-input multiple-output (UM-MIMO) systems and reconfigurable intelligent surfaces, vital for overcoming the distance problem at very high frequencies. We focus on the classical problems of waveform design and modulation, beamforming and precoding, index modulation, channel estimation, channel coding, and data detection. We also motivate signal processing techniques for THz sensing and localization.
