论文摘要
在本文中，我们提出了新的测量结果，以模拟室内和室外场景的Sub-Thz（141-145 GHz）频段（141-145 GHz）带的大规模路径损失，角扩散和通道稀疏性。考虑到视线（LOS）和非视线（NLOS）传播，已经进行了广泛的测量运动。对于所有考虑的传播方案，基于所谓的近距离（CI）自由空间参考距离模型，都开发了Omni方向和方向路径损耗模型。此外，基于该路径损失指数和大规模的阴影褪色估计值，已将路径损耗建模用于第二和第三强多径成分（MPC）。最多使用第三强MPC进一步提出了功率角扩展分析。最后，通过采用所谓的Gini指数，也提出了无线通道稀疏性的结果。
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. Moreover, path loss modeling has been applied for the 2nd and 3rd strongest multipath components (MPCs), based on which path loss exponent and large-scale shadow fading estimates have been derived. A power angular spread analysis is further presented, using up to the 3rd strongest MPC. Finally, results on the sparsity of the wireless channel have also been presented by employing the so-called Gini index.
