GEOMETRY-BASED STATISTICAL MODEL FOR RADIO PROPAGATION IN RECTANGULAR OFFICE BUILDINGS

We present a new approach to the modeling of angle and time of arrival statistics for radio propagation in typical o-ce buildings, in which the majority of interior scattering objects are either parallel or perpendicular to the exterior walls. We flrst describe the reradiating elements in o-ce buildings as randomly distributed arrays of thin strips. The amount of clutter and the amount of transmission/re∞ection loss are then accounted for through several key parameters of the site-speciflc features of indoor environment, such as the layout and materials of the building under consideration. Subsequently, the important channel parameters including power azimuthal spectrum (PAS) and power delay spectrum (PDS) are
