Originální abstrakt

We report results from real-world millimetre wave vehicle-to-vehicle channel measurements carried out in an ur- ban street environment, down-town Vienna, Austria. Channel measurements have been acquired with a time-domain channel sounder in the frequency band 59.75–60.25 GHz with a frequency resolution of approximately 5 MHz. We estimate the local scattering function for sequential stationarity regions in time. A multitaper estimator is used to precisely define Doppler and delay resolutions. Estimates for delay and Doppler profiles are evaluated from the local scattering function for several overtaking vehicles at a variety of speeds and for different types of vehicles. The results show that passenger cars are associated with a single Doppler trajectory, whereas larger vehicles, such as trucks, show up in the data with multiple Doppler trajectories.
