English abstract:
More and more research groups are working on experimental research of millimeter wave (mmWave) wireless communications. Up to now, most mmWave measurements have been carried out in static scenarios. However, as the Doppler effect scales linearly with the carrier frequency, mmWave multicarrier transmission is prone to intercarrier interference caused by Doppler shifts. Today, mmWave radio frequency chipsets (mostly designed for IEEE 802.11ad) are not of as high quality as their centimeter-wave counterparts. Especially the phase noise performance and the noise figure are much worse. Using a testbed with off-the-shelf transmit and receive modules, we show that, depending on the subcarrier spacing, thermal noise or phase noise is dominating the effects of Doppler shifts. Thus, care must be taken in the designing phase of mmWave Doppler measurements.
