毫米波和亚毫米波通信因其巨大的可用带宽而成为未来室内数千兆位无线通信的有前途的解决方案。主要困难之一是人体阻挡效应，因为人体在较低频率下不再被视为“透明”。本文研究了该问题的统计特征。首先，提供人类遮挡的宽带测量。随后，采用人体室内运动的真实移动模型，并在射线发射模拟中应用椭圆柱来近似人体。因此，通过模拟获得视距（LOS）路径和阻塞持续时间以及阻塞数量的分布。最后，评估了分布式天线存在下的系统性能。
The millimeter and sub-millimeter wave communication is a promising solution to future indoor multi-gigabit wireless communications because of its huge available bandwidth. One of the key difficulties is the hu- man blockage effect since the human body can no longer be considered as being "transparent" as at lower frequencies. In this paper a study of statistical characteristics of this problem is presented. At first, broadband measurements of human blockage are provided. Afterwards, a realis- tic mobility model for indoor movements of humans is adopted and elliptic cylinders are applied to approximate human bodies in ray-launching simulations. Consequently, the distributions of Line-Of-Sight (LOS) path and blockage durations as well as blockage numbers are obtained by simulations. Finally, the system performance in presence of the distributed antennas is evaluated.
