Title
Performance of Downlink Spatial-Multiplexing in Urban Macrocellular Multi-User MIMO Scenarios
Abstract
The aim of this paper is to compare the performance of different smart antenna algorithms to the performance of a conventional SISO reference system in an urban multi-user MIMO scenario. A single cell with three 120 deg sectors and several moving users is used for evaluation. The scenario as well as the channel information is generated by means of a realistic urban channel model that consists of a model of the city of Karlsruhe, a mobility model and an accurate ray-tracing based wave propagation model. The smart antenna algorithms under test are two single-user MIMO algorithms (user specific beamforming, waterfilling) and two multi-user MIMO algorithms (block diagonalization, successive optimization). Simulation results show clearly the potential of downlink spatial-multiplexing to improve the system capacity, to reduce the exposure, the transmit power and therefore also the operating costs in future cellular mobile radio systems
