This letter presents an analysis of channel characteristics for an outdoor scenario at the frequency band of 28–30 GHz. A geometry-based clustering algorithm is proposed to group the measured multipath components (MPCs) from the interaction points on the surrounding walls or objects according to ray-tracing three-dimensional (3-D) simulations, giving results that are more physically interpretable than the traditional clustering algorithms. The cluster-level characteristics at 15 positions along a predefined route covering both line-of-sight (LoS) and non-LoS (NLoS) scenarios are investigated. Moreover, power contributions of MPCs with multiple bounces (up to seven bounces in NLoS scenario) from the interaction objects are also investigated.

28、30 GHz 室外测量的基于几何的聚类特性



这封信介绍了 28-30 GHz 频段室外场景的信道特性分析。提出了一种基于几何的聚类算法,根据光线追踪三维 (3-D) 模拟,对来自周围墙壁或物体上的相互作用点的测量多径分量 (MPC) 进行分组,给出的结果在物理上更易于解释传统的聚类算法。研究了覆盖视距 (LoS) 和非 LoS (NLoS) 场景的预定义路线上 15 个位置的集群级特征。此外,还研究了来自交互对象的多次反弹(NLoS 场景中最多七次反弹)的 MPC 的功率贡献。
