Abstract
Most of the studies in the literature about channel modeling do not include
the polarization. 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.
