Aiming to develop a more realistic geometric model including polarization, the channel characteristics are examined using measurement data. Each multipath in the measurement data is modeled with a scatterer. Locations of scatterers are determined in the geometry based single bounce model. Then, each scatterer is replaced by a thin impedance disc. Electrical properties, sizes and orientations of discs are obtained using physical optics approximation. Using the channel model, XPD characteristics of the environment are examined. As a result of this study, a channel model for characterizing the general scenarios as much as possible is developed.xiv, 76 leaves, illustrations, graphsEnglishinfo:eu-repo/semantics/openAccessMultiple Input Multiple Output (MIMO)Ray TracingPhysical Optics (PO)Cross Polarization Discrimination (XPD)PolarizationChannel ModelingTK5103.2 .A55 2008MIMO systems.Wireless communication systems.Thesis
