本文对太赫兹波段（0.1-10太赫兹）通信进行了深入的研究，该技术被认为是满足日益增长的高速无线通信需求的关键技术。太赫兹频段通信将缓解当前无线系统的频谱短缺和容量限制，并在经典网络领域以及新的纳米级通信范式中实现新的应用。本文首先分析了太赫兹波段器件设计和开发面临的挑战。强调了高速收发器架构的局限性和可能的解决方案。介绍了发展新型超宽带天线和超大天线阵列所面临的挑战。当这些设备最终被开发出来时，它们需要在太赫兹波段进行通信。太赫兹波段存在着许多新的通信挑战，如传播建模、容量分析、调制方案以及其他物理层和链路层解决方案等，是通信研究的新前沿。本文对这些挑战进行了深入的讨论，解释了现有的大量工作和仍然需要解决的问题。(C) 2014 Elsevier B.V.版权所有
This paper provides an in-depth view of Terahertz Band (0.1-10 THz) communication, which is envisioned as a key technology to satisfy the increasing demand for higher speed wireless communication. THz Band communication will alleviate the spectrum scarcity and capacity limitations of current wireless systems, and enable new applications both in classical networking domains as well as in novel nanoscale communication paradigms. In this paper, the device design and development challenges for THz Band are surveyed first. The limitations and possible solutions for high-speed transceiver architectures are highlighted. The challenges for the development of new ultra-broadband antennas and very large antenna arrays are explained. When the devices are finally developed, then they need to communicate in the THz band. There exist many novel communication challenges such as propagation modeling, capacity analysis, modulation schemes, and other physical and link layer solutions, in the THz band which can be seen as a new frontier in the communication research. These challenges are treated in depth in this paper explaining the existing plethora of work and what still needs to be tackled. (C) 2014 Elsevier B.V. All rights reserved.
