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.

Results

Routes used in the experiment

Channel impulse response measurement

Channel characterization parameters

WARP board

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.

Operating frequency = 5.8 GHz Relative velocity between two

vehicles = 60 Km/Hr
