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.
