V2V channel characteristics and models for 5 GHz parking garage channels

Vehicle-to-vehicle (V2V) communication channels are of current interest, and these channels have been characterized by both measurements and analysis in several different V2V environments such as highway, urban, and more unique environments such as tunnels. In this paper we extend prior results on the V2V channel in parking garages, based upon measurements taken in two parking garages. We provide results for path loss, delay spread, small-scale fading, and models for the 10-MHz V2V channel in the form of tapped delay parameters, for both line-of-sight and non-line-of-sight conditions.
