We modeled human-induced shadowing events, when 1-7 pedestrians block the line-of-sight (LOS) in an access point (AP) to user station (STA), operating at 60 GHz, for two types of scenarios: controlling the trajectories of pedestrians, and a non-controlled case. Deep shadowing events only occurred when pedestrians crossed the LOS in both cases, which means that the effect of blocking reflected or scattered signals was negligible. For the controlled scenario (when multiple pedestrians crossed the LOS simultaneously) we observed that once the closest positions to the STA were blocked, the effect of blocking the rest of the link were only marginal. We also tested two antenna-aiming strategies at the STA. We observed that once the antenna gain is normalized and oriented towards the AP, there are no significant penalties by aligning the antenna in the horizontal plane only. We also report results to parameterize single and sequences of shadow fades, that are useful for simulation purposes and to validate theoretical models

本研究针对两类场景建模了行人引发的遮挡事件：当1至7名行人阻断工作于60 GHz频段的接入点（Access Point, AP）至用户站（User Station, STA）之间的视距（Line-of-Sight, LOS）链路时，一类场景为行人轨迹可控，另一类为非受控场景。两类场景中，仅当行人横穿视距链路时才会发生深度遮挡事件，这意味着阻断反射或散射信号的影响可忽略不计。针对行人轨迹可控的场景（多名行人同时横穿视距链路的情况），我们观测到：当用户站的最邻近位置被遮挡后，链路其余部分的遮挡影响仅为边际性的，即影响十分有限。我们还在用户站上测试了两种天线对准策略，观测结果显示：当日线增益归一化且朝向接入点时，仅在水平面内对准天线不会带来显著的性能损失。本研究还给出了单次及序列性阴影衰落的参数化结果，此类结果可用于仿真实验与理论模型验证。
