论文摘要
在本文中,通过广泛的射线追踪(RT)模拟来表征28 GHz的室内密集空间(IDS)通道。我们将ID视为具有密闭几何形状的特定类型的室内环境,并装有人类,例如飞机舱和火车货车。基于RT模拟,我们表征路径损失,阴影褪色,根平方延迟扩散,RICIAN K因子,方位角/高程到达/出发的角度传播,考虑到机身几何形状,物质和人类存在的不同RT模拟场景。尽管大规模褪色参数与最新的通道模型相似,但小规模的褪色参数显示ID中的较丰富的多径散射,导致与3GPP室内通道模型相比,位错误率较差。
In this paper, the indoor dense space (IDS) channel at 28 GHz is characterized through extensive Ray-Tracing (RT) simulations. We consider IDS as a specific type of indoor environment with confined geometry and packed with humans, such as aircraft cabins and train wagons. Based on RT simulations, we characterize path loss, shadow fading, root-mean-square delay spread, Rician K-factor, azimuth/elevation angular spread of arrival/departure considering different RT simulation scenarios of the fuselage geometry, material, and human presence. While the large-scale fading parameters are similar to the state-of-the-art channel models, the small-scale fading parameters demonstrate richer multipath scattering in IDS, resulting in poorer bit error rate performance in comparison to the 3GPP indoor channel model.
