MIMO Channel Capacity Computed with 3D Ray Tracing Model

Abstract:
Future wireless communication systems are expected to offer highly reliable broadband radio access in order to meet the increasing demands of emerging high speed data and multimedia services. In recent years information theoretic investigations have shown that multiple-input multiple-output (MIMO) systems can support extremely high data rates within rich scattering environments. To design high efficient MIMO wireless systems and predict system performance under various circumstances accurate MIMO wireless channel models for different scenarios are required. Recently, standardized double directional stochastic MIMO channel models have been proposed for different scenarios based on the statistical information evaluated from measured data. However, statistical channel models are based on measurement campaigns and therefore only valid for the measured scenarios. In this paper the MIMO channel capacity has been evaluated using deterministic channel modeling. A three dimensional ray tracing package has been utilized for the determination of the propagation paths and further crucial parameters of the radio channel, such as the angular spread at both base and mobile station.
