Abstract

In this paper, an indoor propagation channel model for a MIMO (multi-input multi-output) system at the 5 GHz band is presented. 3D ray tracing and a patch scattering model are primarily used in order to take the indoor fixtures into account. Therefore, input parameters, such as indoor environment parameters and types of antenna are considered. In the results, the PDP (power delay profile) and AOA (angle of arrival) are presented, and the RDS (RMS delay spread) and AS (angular spread) are calculated from them. In order to verify the accuracy of the proposed model, simulated results are compared with measurements in an actual indoor environment. Estimated eigenvalues for MIMO channel characteristics are also represented.
