Multipath Cluster Polarization Characteristics of a Small Urban MIMO Macrocell

Free registration required

Executive Summary

This paper presents clusterwise polarization characteristics taken from an estimated MIMO channel of a small urban macrocell at 4.5 GHz. Polarization path gain, cross-polarization ratio, and co-polarization ratio characteristics as influenced by channel parameters such as delay, azimuth and elevation angle of arrival were investigated. The results showed that polarization characteristics were almost independent of the azimuth angle of arrival and delay, whereas some correlation was found between the cross-polarization ratio and the elevation angle of arrival. The results also confirmed a log-normal cross-polarization ratio.
