论文摘要
Terahertz（THZ）-band Communications是未来生成无线通信系统的关键推动力，该系统有望集成广泛的数据需求应用程序。光子，电子和等离子技术的最新进展正在缩小THZ收发器设计中的差距。因此，前景THZ信号的产生，调制和辐射方法正在融合，相应的通道模型，噪声和硬件损失概念正在出现。这样的进展为无线通信的特定特定信号处理技术的研究建立了良好的研究基础。本教程概述了这些技术，强调了超质量的多输入多输出（UM-MIMO）系统和可重新配置的智能表面，对于在非常高的频率下克服距离问题至关重要。我们专注于波形设计和调制，波束形成和预编码，索引调制，通道估计，通道编码和数据检测的经典问题。我们还激励信号处理技术用于THZ感应和本地化。
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.
