Abstract
The scattering environment in vehicle-to-vehicle communication channels at 5.2 GHz changes rapidly. Hence the

wide-sense stationary (WSS) uncorrelated scattering (US) assumption for the fading process is valid for short time

intervals only. We characterize the spectral divergence of the local scattering function (LSF) sequence in order to

assess the non-WSSUS characteristics in different scenarios. We find that the vehicle-to-vehicle channels violate the

wide-sense stationarity much stronger than the US assumption. Additionally, we use the LSF to quantify the time

dependence of the channel coherence time and bandwidth. Both parameters vary strongly over time depending on the

chosen... (More)

dependence of the channel coherence time and bandwidth. Both parameters vary strongly over time depending on the

chosen scenario. Furthermore the effect of the antenna radiation pattern on the fading process is quantified, which can

cause the strength of a multipath component to change by more than 40 dB in drive-by experiments. (Less)
