宽带信道仿真是测试5G毫米波系统的关键组成部分。在本文中，我们使用信道探测系统来验证先前为5G毫米波系统的性能评估和验证而设计的新型实时硬件在环（HIL）宽带信道模拟器。采用了新颖的频谱拼接和信道划分技术，设计了HIL系统。该HIL平台在时域和频域进行了校准和验证。然后，我们将使用一对60GHz毫米波调制解调器的结果与通过RF通道模拟器通过宽带I/Q上下转换连接的毫米波调制解调器的结果进行背靠背比较。最后，模拟了加性高斯白噪声（AWGN）信道的路径损耗，以表征使用毫米波调制解调器进行定点对点部署时的数据吞吐量与信噪比（SNR）的关系。
Wideband channel emulation is a key component to testing 5G mmWave systems. In this paper we use a channel sounding system to validate a novel real-time Hardware-In-the-Loop (HIL) wideband channel emulator previously designed for the performance evaluation and verification of 5G mmWave systems. The HIL system was designed using novel spectral stitching and channel partitioning. The HIL platform is calibrated and validated in both the time and frequency domains. We then compare back-to-back results using a pair of 60GHz mmWave modems with results for the mmWave modems connected through the RF channel emulator via wideband I/Q up and down conversion. Finally, emulated path loss was generated for an Additive White Gaussian Noise (AWGN) channel to characterize the data throughput versus Signal-to-Noise Ratio (SNR) for a fixed point-to-point deployment using the mmWave modems.
