论文摘要
在这项工作中，我们显示了用于毫米波设备的空中测试的测试床的设计和验证。我们已经将能够模拟非平稳通道的基带通道模拟器的频率功能扩展到更高的频率。为了确保在测试中的设备与模拟器的RF-Frontend之间的传播只是一个视线链接，我们已经在两个无声室中隔离了测试以下的设备。我们通过两种人造情况的频率扫描以57 GHz的速度表征测试床：当模拟器复制一个TAP通道和两个TAP通道时。最后，我们通过在2018年在维也纳进行的车辆毫米浪潮测量运动中获取的渠道来证明系统功能。
In this work, we show the design and validation of a testbed for over-the-air testing of millimetre waves equipments. We have extended the frequency capabilities of a baseband channel emulator which is capable of emulating non-stationary channels, to higher frequencies. To assure that the propagation between devices-under-test and the RF-frontend of the emulator is only a line-of-sight link, we have isolated the devices-under-test in two anechoic chambers. We characterize the testbed at 57 GHz by means of frequency sweeps for two artificial cases: when the emulator is replicating a one-tap channel and a two-tap channel. Finally we demonstrate the system functionality through reproduction of channels which were acquired during a vehicular millimetre wave measurement campaign conducted in Vienna in 2018.
