Car-to-Car Radio Channel Measurements at 5 GHz: Pathloss, Power-Delay Profile, and Delay-Doppler Sprectrum

We carried out a car-to-infrastructure (C21) and car-to-car (C2C) 4X4 multiple-input multipleoutput (MIMO) radio channel measurement campaign at 5.2 GHz in Lund, Sweden. This paper presents first results on pathloss, power-delay profiles, and delay-Doppler spectra in a C2C highway scenario, where both cars were traveling in opposite directions. A pathloss coefficient of 1.8 yields the best fit with our measurement results in the mean square sense. The measured Doppler shift of the line of sight path matches exactly with theoretical calculations. Selected paths are investigated in the delay and Doppler domain. The average delay spread is 250 ns; Doppler shifts of more than 1000 Hz are observed. ISWCS 2007 This work may not be copied or reproduced in whole or in part for any commercial purpose.
