摘要

This paper deals with evaluating the effect of vehicle vibrations on the mm-wave intra-vehicular channel. As some of the vehicles' vibration amplitude may reach the order of millimeters, i.e., the amplitude is comparable with the mm-wave wavelength (≈5 mm), it can produce severe Doppler spreads. This paper evaluates Doppler spreads utilizing a mm-wave time-domain correlative channel sounder built into a vehicle which has been driven at different speeds on a variety of roads with a broad spectrum of surface quality.
