Abstract

THz band communication has the potential to meet the high data rate demands of many current and future applications. However, before these networks are realized, extensive channel measurements are needed in order to characterize the wireless channel at these frequencies, in order to inform system design and deployment. In the current paper, we present a set of double-directional channel measurements that are conducted in several relevant indoor and outdoor scenarios. Our aim is to see the effect of common building materials that might be particularly reflective or absorptive (such as energy-saving glass, window blinds, or metallic reflectors), and how their presence changes the channel characteristics. Among other effects we find that - depending on the considered dynamic range - presence/absence of these materials can increase the required equalizer length by an order of magnitude.

摘要

太赫兹频段通信有潜力满足许多当前和未来应用对高数据速率的需求。然而，在这些网络实现之前，需要进行广泛的信道测量，以便表征这些频率下的无线信道，为系统设计和部署提供依据。在本文中，我们展示了一组在多个相关室内和室外场景中进行的双向信道测量。我们的目的是观察可能具有特别反射性或吸收性的常见建筑材料（如节能玻璃、百叶窗或金属反射器）的影响，以及它们的存在如何改变信道特性。在其他影响中我们发现，根据所考虑的动态范围，这些材料的存在与否会使所需均衡器长度增加一个数量级。
