Experimental frequency dispersion study of the vehicular-to-vehicular propagation channel

In this work, we perform an experimental study of the received envelope autocorrelation and the power spectrum density (PSD) of the vehicular-to-vehicular (V2V) propagation channel. The coherence time and Doppler spread have been derived from narrowband channel measurements at 5.9 GHz. The measurements have been collected in urban and highway environments under real road traffic conditions. The relationship of the coherence time and Doppler spread between the effective speed of the Tx and Rx is investigated. The values of the coherence time and Doppler spread reported here can be useful for protocols evaluation and future vehicular networks design.
