Abstract

In this paper, we present new measurement results to model large-scale path loss, angular spread and channel sparsity at the sub-THz (141–145 GHz) band, for both indoor and outdoor scenarios. Extensive measurement campaigns have been carried out, taking into account both line-of-sight (LoS) and non line-of-sight (NLoS) propagation. For all considered propagation scenarios, omni-directional and directional path loss models have been developed, based on the so-called close-in (CI) free-space reference distance model. A power angular spread analysis is further presented. The sparsity of the wireless channel has also been studied by employing suitable metrics, namely the so-called Gini index (GI), the Ricean K-factor and the root mean square (RMS) delay spread.

亚千赫频段室内和室外环境的路径损耗、角展和信道稀疏性建模

在本文中，我们介绍了新的测量结果，以模拟亚 THz（141-145 GHz）频段室内和室外场景下的大规模路径损耗、角展和信道稀疏性。考虑到视距（LoS）和非视距（NLoS）传播，进行了广泛的测量活动。针对所有考虑到的传播场景，根据所谓的近距离（CI）自由空间参考距离模型，开发了全向和定向路径损耗模型。还进一步提出了功率角传播分析。此外，还采用了适当的指标，即所谓的基尼指数（GI）、Ricean K 因子和均方根（RMS）延迟传播，对无线信道的稀疏性进行了研究。
