Non-WSSUS Vehicular Channel Characterization at 5.2 GHz - Spectral Divergence and Time-Variant Coherence Parameters
(2008) XXIXth URSI General Assembly 2008- 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) - The scattering environment in vehicle-to-vehicle communication channels at 5.2 GHz changes rapidly. Hence the

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