Channel Characterization for 700 MHz DSRC Vehicular Communication

الملخص EN

Adapting OFDM for vehicular communication requires extensive knowledge of anticipated multipath and Doppler environments.

We present a GPS-enabled channel sounding system built and used to conduct a channel measurement campaign.

Tests conducted at the 700 MHz band in and around downtown Ann Arbor, Michigan, explored various vehicle-to-vehicle and vehicle-to-roadside channel scenarios.

The measured channel metrics are used to quantify the effects on guard interval, packet duration, and subcarrier spacing for a functional OFDM system at 700 MHz.

This paper is one of the first to present vehicular-based channel-modeling results from measured data in the 700 MHz band.
