Abstract

Adapting OFDM for vehicular communicationrequires extensive knowledge of anticipated multipath andDoppler environments. We present a GPS-enabled channelsounding system built and used to conduct a channelmeasurement campaign. Tests conducted at the 700 MHzband in and around downtown Ann Arbor, Michigan,explored various vehicle-to-vehicle and vehicle-to-roadsidechannel scenarios. The measured channel metrics are usedto quantify the effects on guard interval, packet duration,and subcarrier spacing for a functional OFDM systemat 700 MHz. This paper is one of the first to presentvehicular-based channel-modeling results from measureddata in the 700 MHz band.
