One Indoor Channel Model per Cluster for MIMO Systems Polarized

Abstract

cluster channel model for an indoor environment, which includes the characterization of polarization, is presented in this work. A measurement campaign was carried out in an indoor environment at 3.6 GHz, with a bipolarized transmitter and a 3-pole receiver. The rays are detected with the SAGE algorithm, and cross-polar discrimination (XPD) per ray is defined. Clusters are identified in the azimuth - elevation - delay domains, with an automatic clustering algorithm. The properties of the clusters are investigated and polarization characteristics by cluster are extracted. The obtained model is simulated, and the independent parameters are compared with the measurements for validation. The results indicated that the XPDs of the rays have a lognormal distribution per cluster.
