摘要

本文介绍了利用 300 GHz 时域信道探测进行的全面双向信道测量,以描述数据中心无线链路的信道特征。信道被分为三种不同的使用情况,并根据未来通信系统所需的信噪比对信道参数进行了单独分析。信道的空间和时间分析揭示了相关的传播效应,如散射的影响,并推导出传播的信道参数与无线电信道之间的关系。分析表明,尽管采用了高增益定向天线,多径传播仍与高信噪比要求的系统相关。对相关传播效应的一阶近似是对分析的补充。包括所有元数据在内的 18250 个校准脉冲响应的整个测量活动的测量数据已经公布,以便研究界共同受益。

Channel Measurements at 300 GHz for Low Terahertz Links in a Data Center
This article presents comprehensive double-directional channel measurements with time-domain channel sounding at 300 GHz that characterize the channel of wireless links in a data center. The channels are classified into three scenario-dependent use cases and are individually analyzed providing channel parameters as a function of the required signal-to-noise ratio of the prospective communication system. The spatial and temporal analysis of the channel reveals relevant propagation effects such as the influence of scattering and derives relations between the channel parameters of the propagation and the radio channel. The analysis shows that multipath propagation becomes relevant for systems with high signal-to-noise ratio requirements despite high-gain directional antennas. A first order approximation of relevant propagation effects complements the analysis. The measurement data of the whole measurement campaign with 18250 calibrated impulse responses including all meta data is published so that the research community has a collective benefit.
