由于数据速率不断提高，未来的5G移动的网络将需要在更高的频率和带宽下运行。为了研究这些网络的新技术，信道探测对于测量和分析时变阴影环境下单用户和多用户情况下的多径传播是必不可少的。这就要求毫米波（mm波）信道探测器（CS）的设计具有挑战性-它必须提供具有多个天线和高动态范围的超宽带（UWB）实时操作。另外，例如，对于在移动终端处的极化未对准的情况，需要极化信息来完全解调无线信道。本文提出了一种新的UWB双极化毫米波信道探测器架构，用于5G移动的网络中的真实的时间测量，并激发了在60 GHz下收集实验数据进行极化测量的需求。
Owing to the increasing data rates, future 5G mobile networks will need to operate at higher frequencies and bandwidths. To investigate new techniques for those networks, channel sounding is essential for measuring and analysing the multipath propagation in single and multi-user situations under time-variant shadowing environments. This requires a challenging design of the millimeter-wave (mm-wave) channel sounder (CS) - it must provide ultra-wideband (UWB) real-time operation with multiple antennas and a high dynamic range. In addition, polarimetric information is needed to fully characterise the wireless channel, e.g. for cases of polarisation misalignment at the mobile device. This paper presents a novel UWB dual-polarised mm-wave channel sounder architecture for real time measurements in 5G mobile networks and motivates the need for polarimetric measurements with experimental data collected at 60 GHz.
