In this paper the autocorrelation properties of shadow fading and angle spread at both the Base Station (BS) and at the Mobile Station (MS) are analyzed using urban macro cellular measurement data. The shadow fading parameter is shown to have a longer de correlation distance than the angle spread at both the BS and at the MS. Furthermore, the authors observe variations in the shadow fading that depend on the direction of the MS movement due to street canyons. The same dependence is not observed in the angle spreads. These results indicate that the origin of the angle spread is local to the transmitter and receiver, while the shadow fading depends on the intermediate environment.
