摘要

90ghz以上的频谱是一个很有前途的研究领域,可以提供超越IMT 2020的性能,如100+ Gbit/s数据速率或亚毫秒延迟的未来无线网络。特别是巨大的可用带宽可以服务于未来超密集部署的回程传输网络,以及大量的前传数据流。本文研究了街道内亚太赫兹网格回运的可行性和特点。该研究依赖于对物理层性能的高度逼真的模拟,基于详细的地理表示、基于射线的传播建模、射频相位噪声损伤和一种新的对相位噪声具有鲁棒性的调制方案。研究了可实现的吞吐量,表明密集网状回程网络的每条链路在1 ghz载波带宽下可以可靠地传输数Gbit/s。评估了多径多样性,以及降雨和相位噪声水平的影响。

Investigating sub-THz PHY layer for future high-data-rate wireless backhaul
Spectrum above 90 GHz is a promising investigation domain to offer future wireless networks with performance beyond IMT 2020 such as 100+ Gbit/s data rate or sub-ms latency. In particular, the huge available bandwidth can serve the backhaul transport network in the perspective of future ultra-dense deployments, and massive front-haul data streams. This paper investigates the feasibility and characteristics of the in-street sub-THz mesh backhauling. The study relies on the highly realistic simulation of the physical layer performance, based on detailed geographical representation, ray-based propagation modelling, RF phase noise impairment, and a new modulation scheme robust to phase noise. The achievable throughput is studied, and it is shown that each link of a dense mesh backhaul network can reliably deliver several Gbit/s per 1-GHz carrier bandwidth. The multi-path diversity is assessed, as well as the impact of rainfall and phase noise level.

期刊介绍: The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
