Objective: In this paper, a platform for measuring the channel characteristics for vehicle to vehicle (V2V) communica-tions is presented. The platform is developed using Rice University Wireless Open-Access Research Platform (WARP) boards and utilized to perform an experimental study of V2V channel through conducting field measurements.

Doppler spectrum: relates to the coherence
time of the channel.
Power delay profile: to characterize the mul-
tipath nature of the channel.
Spatial correlation: describes the correla-tion between Tx anten-nas and Rx antennas.
