Inter- and intrasite correlations of large-scale parameters from macrocellular measurements at 1800 MHz

Abstract

The inter- and intrasite correlation propertiesof shadow fading and power-weighted angle spreadat both the mobile station and the base station are studiedutilizing narrowband multisite MIMO measurements in the1800 MHz band. The influence of the distance between two basestations on the correlation is studied in an urban environment.Measurements have been conducted for two different situations:widely separated as well as closely located base stations. Novelresults regarding the correlation of the power-weighted anglespread between base station sites with different separations arepresented. Furthermore, the measurements and analysis presentedherein confirm the autocorrelation and cross-correlationproperties of the shadow fading and the angle spread that havebeen observed in previous studies.
