无线电信道测量是无线通信网络设计的基础。由于需要更高的数据速率来提供沉浸式用户体验，并且异构网络预计将主导下一代蜂窝网络，因此需要多频带信道探测器来为此类系统的设计提供必要的测量。在本教程中，概述了从TV频段低频到毫米波频段的多个频段中宽带信道探测的要求。最先进的信道探测器架构，使主动无线电传播测量和被动频谱监测的国家的例子进行了讨论。通过使用单个或多个天线发射宽带信号和使用单个或多个天线接收来实现主动测量，以表征诸如时延扩展和角扩展之类的多径参数。路径损耗和阴影效应的估计也能够通过这样的测量。随着对频谱效率的需求增加，用于认知无线电应用的频谱感测的重要性日益增加。采用快速频率扫描的信道探测器可以在被动模式中使用，以感测频谱的占用，并在空间、时间和频率上对频谱的可用性进行建模和预测。
Radio channel measurements are fundamental for the design of wireless communication networks. As higher data rates are required to provide immersive user experiences and heterogeneous networks are expected to dominate the next generation of cellular networks, multi-band channel sounders are needed to provide the necessary measurements for the design of such systems. In this tutorial the requirements of wideband channel sounding in multiple bands from low frequencies in the TV band to the mmWave band are outlined. Examples of state of the art channel sounder architectures which enable both active radio propagation measurements and passive spectrum monitoring are discussed. Active measurements are enabled through the transmission of a wideband signal using either single or multiple antennas and reception with either single or multiple antennas for the characterisation of multipath parameters such as time delay spread and angular spread. The estimation of path loss and shadowing effects are also enabled through such measurements. As the demand for spectrum efficiency increases, spectrum sensing for cognitive radio applications is increasing in importance. Channel sounders which employ a fast frequency sweep can be used in the passive mode to sense the occupancy of the spectrum and to model and predict the availability of the spectrum in space, time and frequency.
