毫米波（mmWave）频率为巨大容量的无线链路提供了潜力。然而，在这些频率下设计鲁棒的通信系统需要我们了解时间和空间上的信道动态：毫米波信号非常容易受到阻塞，因此信道可以随着障碍物和反射器的微小移动而迅速出现和消失。在丰富的散射环境中，不同的路径可能会遇到不同的阻塞轨迹和了解这些多路径阻塞动态是必不可少的开发和评估波束成形和波束跟踪算法。本文介绍了一种新的测量系统，它使用相控阵列进行毫米波动态信道测量的设计和实验结果。具体而言，人的阻塞和它的影响，在多个路径进行调查，只有几个微秒之间的连续测量。从这些测量，我们开发了一种建模技术，使用低秩张量分解分离可用的路径，使他们的联合统计可以理解。
The millimeter wave (mmWave) frequencies offer the potential for enormous capacity wireless links. However, designing robust communication systems at these frequencies requires that we understand the channel dynamics over both time and space: mmWave signals are extremely vulnerable to blocking and the channel can thus rapidly appear and disappear with small movement of obstacles and reflectors. In rich scattering environments, different paths may experience different blocking trajectories and understanding these multi-path blocking dynamics is essential for developing and assessing beamforming and beam-tracking algorithms. This paper presents the design and experimental results of a novel measurement system which uses phased arrays to perform mmWave dynamic channel measurements. Specifically, human blockage and its effects across multiple paths are investigated with only several microseconds between successive measurements. From these measurements we develop a modeling technique which uses low-rank tensor factorization to separate the available paths so that their joint statistics can be understood.
