Abstract :
The paper presents a geometry-based MIMO channel model for outdoor-to-indoor applications. The propagation channel model is derived when indoor scatterers are located on a hollow-disk around the user and a distribution of outdoor scatterers exists between the base station and the user. The closed-form Cross-Correlation Function (CCF) is derived for the aforementioned scenario. This function depends on various parameters of interest including the distance between the base station and the user, the spacing among antennas elements, and the directions of the antennas elements. The numerical CCF values are obtained with Radiowave Propagation Simulator (RPS) software for the building of Electrical and Computer Engineering School at the University of Sistan and Baluchestan. The results show that considering the outdoor scatterers increases the accuracy of the CCF and the capacity computation significantly.
