Summary:
This work presents a quasi-three dimensional scattering model to predict the polarization properties of an indoor radio channel. The proposed model considers not only the effect of the polarization of fields scattered by scatterers but also extends the ellipse model to a quasi-three dimensional model. In the model, all scatterers are considered as a patch scatterer and distribution properties of the angle and delay correspond with those of an ellipse model. Vertical and horizontal ellipse planes are employed to consider the floor, ceiling, walls, and extraneous structures. For a realistic indoor channel model, multi ellipses are defined so as to incorporate indoor channel properties. Investigation of the polarization matrix of the model is conducted in terms of cross-polarization discrimination (XPD) and MIMO capacity by the Monte-Carlo method. The results demonstrate that the model can predict various properties for multi-polarized antennas.
