Non-WSSUS vehicular channel characterization in highway and urban scenarios at 5.2 GHz using the local scattering function
The fading process in high speed vehicular traffic telematic applications at 5 GHz is expected to fulfill the wide-sense stationarity uncorrelated scattering (WSSUS) assumption for very short time-intervals only. In order to test this assumption we apply the concept of a local time– and frequency–variant scattering function, which we estimate from measurements of vehicle-to-vehicle wave propagatio
