Experimental and Analytical Characterization of Time-Variant V2V Channels in a Highway Scenario

The time-variant characteristic of the vehicle to vehicle channel is discussed using measurements at 2.53 GHz from a highway scenario. For typical use cases, spectrograms in the time-delay as well as the Doppler domain are shown based on sequences of the generalized local scattering function. Delay-Doppler-bounds to be expected for single bounce reflections are determined by known movements of the transmitter and receiver using a channel representation in a prolate spheroidal coordinate system. Dominant moving scatterers are identified by visual inspection using proper meta data.
