克服毫米波和太赫兹频段的距离问题

Combating the Distance Problem in the Millimeter Wave and Terahertz Frequency Bands

Ian F. Akyildiz, Chong Han, Shuai Nie

摘要:

在毫米波(30-300 GHz)和太赫兹(0. 1 -10 THz)频段中,高的扩频损耗和分子吸收往往限制了信号的传输距离和覆盖范围。本文研究了解决距离限制这一关键问题的四个方向,即物理层距离感知设计、超大规模大规模多输入多输出通信、反射阵列和智能表面。此外,提出了这些技术的潜在联合设计,以结合这些优点并可能进一步扩展通信距离。定性分析和定量模拟,以说明所提出的技术的好处,并证明了毫米波和太赫兹波段通信的可行性高达100米的视线和非视线区域。

英文摘要:

In the millimeter wave (30-300 GHz) and Terahertz (0.1-10 THz) frequency bands, high spreading loss and molecular absorption often limit the signal transmission distance and coverage range. In this paper, four directions to tackle the crucial problem of distance limitation are investigated, namely, a physical layer distance-aware design, ultra-massive MIMO communication, reflectarrays, and intelligent surfaces. Additionally, the potential joint design of these technologies is proposed to combine the benefits and possibly further extend the communication distance. Qualitative analyses and quantitative simulations are provided to illustrate the benefits of the proposed techniques and demonstrate the feasibility of mm-wave and THz band communications up to 100 meters in both line-of-sight and non-line-of-sight areas.
