论文摘要
在低6 GHz和毫米波（MMWAVE）频段中，传播通道特性大不相同。典型的MMWave链接的经历不仅仅是较大的路径损失，而且比传统的6 GHz链路更容易受到阻塞。因此，需要进行高效的通道探空仪的广泛测量活动，以完全了解MMWave传播渠道特征。此外，应寻求解决方案来克服与MMWave频段相关的中断问题并实现可接受的沟通性能。在本文中，我们引入了我们的28 GHz通道音响器，可与Horn天线以及相位的阵列天线一起使用。然后将两种天线类型从一个方向切换到另一个方向，然后提取的多径成分（MPC）属性（例如路径增益）进行比较。然后，我们建议使用被动反射器和主动中继器通过提高接收的信号强度来增强覆盖范围。特别是引入了回声反射器和涡轮中继器，并提出了使用它们的测量结果。
Propagation channel characteristics are substantially different in sub-6 GHz and millimeter-wave (mmWave) bands. A typical mmWave link experiences more than an order-of-magnitude larger path loss and is more susceptible to blockages than a traditional sub-6 GHz link. Therefore, extensive measurement campaigns with efficient channel sounders are needed for a complete understanding of the mmWave propagation channel characteristics. In addition, solutions should be sought to overcome the outage problems associated with the mmWave bands and to achieve acceptable communication performance. In this paper, our 28 GHz channel sounder is introduced that can be used with horn antennas as well as phased array antennas. The two antenna types are then compared in terms of speed they switch from one direction to another and extracted multipath component (MPC) properties, such as path gain. We then propose the use of passive reflectors and an active repeater for coverage enhancement by improving the received signal strength. In particular, ECHO reflector and TURBO repeater are introduced, and measurement results using them are presented.
