Vehicle-to-vehicle radio channel characterization in urban environment at 2.3 GHz and 5.25 GHz

In this paper, we present the channel measurement results of vehicle-to-vehicle (V2V) measurement campaign carried out in Oulu city center, Finland. The measurements were conducted with EB Propsound CS^TM at 2.3 GHz and 5.25 GHz center frequencies. The antennas were installed on the roof of the vehicles and the measurements were performed for single-input multiple-output (SIMO) antenna configuration. The campaign results are presented in the form of path loss, delay spread (DS), maximum excess delay, the standard deviation of slow fading (SF) and K-factor. Furthermore, we propose the method for calculating correlation distance for large scale parameters in V2V channel and present the results for correlation distances of SF, DS and K-factor. The correlation distances less than 11 meters were observed.
