标题： Broadband measurements and analysis of human blocking in a 60 GHz indoor radio channel

摘要： 新的毫米波无线通信系统可能会受到人体引入的阻塞的显著影响。 在60 GHz频率下，由于传播损耗较高，这些系统的覆盖范围相对有限。 因此，波束成形可以用来找到一个反射路径来替代被阻塞的路径。 在本研究中，研究重点是会议室中人体阻塞的影响，以评估人体在60 GHz下引入的阻塞损耗。 在路径损耗和信道冲击响应方面的结果表明，人体引起的衰减在24到26 dB之间。 此外，结果表明，使用波束成形可以利用反射路径来替代可能被人体阻塞的直射链路。 显示英文摘要

摘要： New millimeter-wave wireless communication systems can be strongly impacted by the blockage introduced by the human body. At 60 GHz, the coverage of these systems is relatively limited due to high propagation losses. Thus, beamforming allows to find a reflective path to replace the blocked one. In this work, the study focuses on the impact of a human blocker in a meeting room, to evaluate the blocking losses introduced by the human body at 60 GHz. The results obtained in terms of path loss and channel impulse response show that the attenuation by the human body is between 24 and 26 dB. Moreover, the results show that the use of beamforming allows to exploit the reflected paths to replace the direct link that can be blocked by the human body.
