Abstract

Terahertz (THz) communications has been envisioned as an enabling and highly promising technology for the sixth generation (6G) and beyond wireless networks which aim to provide full and unlimited wireless connectivity for the ubiquitous intelligent information society of 2030 and beyond. In particular, the ultra-wide THz band from 0.1 to 10 THz offers enormous potential to alleviate the spectrum scarcity and break the capacity limitation of emerging wireless systems, such as the fifth generation (5G) wireless networks. This will undoubtedly support epoch-making wireless applications that demand ultra-high quality of service requirements and multi-terabits/s data transmission in the 6G and beyond era, such as holographic communications, immersive extended reality, ultra-fast backhaul and wireless local area networks, and wireless high-bandwidth secure transmission. Moreover, THz transceivers and antennas boast an incredibly compact size, reaching sub-millimetric dimensions. This miniaturization enables the seamless integration of extremely small radios into various environments, giving rise to ground-breaking applications, e.g., the Internet of Nano-Things and wireless networks-on-chip. Furthermore, the utilization of the THz band extends beyond traditional radar and localization, opening doors to novel wireless sensing capabilities and underpinning cutting-edge applications such as healthcare nano-bio-sensing. Due to the aforementioned advantages, an unprecedented amount of spectrum within the 0.275–0.45 THz band was opened for land mobile and fixed service in 6G after World Radio Conference 2019. Additionally, the IEEE 802.15.3 d standard has been established as the first wireless standard in the sub-THz band (specifically, 253–322 GHz) to support data rates of 100 gigabit/s and above.

6G及以后网络中太赫兹通信的高级信号处理客座编辑
太赫兹(THz)通信已被设想为第六代(6G)及以后无线网络的一种赋能且极具前景的技术,其目标是为2030年及以后无处不在的智能信息社会提供完全和无限的无线连接。特别是,0.1至10THz的超宽THz频段为缓解频谱稀缺和打破新兴无线系统(如第五代(5G)无线网络)的容量限制提供了巨大的潜力。这无疑将支持划时代的无线应用,这些应用在6G及以后的时代需要超高的服务质量要求和数万亿比特/秒的数据传输,如全息通信、沉浸式扩展现实、超快回程和无线局域网,以及无线高带宽安全传输。此外,太赫兹收发器和天线拥有令人难以置信的紧凑尺寸,达到亚毫米尺寸。这种小型化使极小的无线电能够无缝集成到各种环境中,从而产生了开创性的应用,例如纳米物联网和芯片上无线网络。此外,太赫兹波段的利用超越了传统的雷达和定位,为新型无线传感能力打开了大门,并为医疗保健纳米生物传感等尖端应用奠定了基础。由于上述优势,在2019年世界无线电大会之后,0.275–0.45 THz频带内前所未有的频谱数量被开放用于6G的陆地移动和固定服务。此外,IEEE 802.15.3 d标准已被确立为亚太赫兹频带(具体而言,253–322 GHz)中的第一个无线标准,以支持100吉比特/秒及以上的数据速率。

期刊介绍: The IEEE Journal of Selected Topics in Signal Processing (JSTSP) focuses on the Field of Interest of the IEEE Signal Processing Society, which encompasses the theory and application of various signal processing techniques. These techniques include filtering, coding, transmitting, estimating, detecting, analyzing, recognizing, synthesizing, recording, and reproducing signals using digital or analog devices. The term "signal" covers a wide range of data types, including audio, video, speech, image, communication, geophysical, sonar, radar, medical, musical, and others. The journal format allows for in-depth exploration of signal processing topics, enabling the Society to cover both established and emerging areas. This includes interdisciplinary fields such as biomedical engineering and language processing, as well as areas not traditionally associated with engineering.
