Channel Correlation and Stationarity in mm-wave V2V Channels

This paper investigates different methods to estimate the channel correlation properties over time for millimeter wave (mm-Wave) vehicle-to-vehicle (V2V) channels. The proposed metrics are applied on three V2V scenarios measured at 26 GHz. The correlation properties are derived from the Power Delay Profile (PDP) and the Local Scattering Function (LSF). The results are then analyzed in terms of quasi-stationary time intervals obtained from each approach.
