Propagation channel cluster characteristics

In this paper, propagation channel cluster characteristics, such as azimuth angle spread, lifetimes, and polarization properties, were analysed. All the analysed data was measured in typical urban microcellular environment, and the parameters of the clusters were extracted manually after beamforming processing. The AS difference between LOS and NLOS in 2 GHz with 50% level was approximately 4.6deg and in 5 GHz only 0.9deg. The number of long-lived clusters varied between 1-4, and there was only small coupling from vertical to horizontal polarization.
