Abstract :
Cross-correlation of multiuser shadowing in an indoor environment at 2.55 GHz is presented, indicating that shadowing is mostly uncorrelated after 2-4 m in the indoor environment. Similar shadowing correlation was obtained for autocorrelation measurements, moving primary (versus moving secondaries), as well as near and far primary measurements.
