A modelling approach for multiuser MIMO systems including spatially-colored interference [cellular example] |
Abstract | ||
|---|---|---|
This paper deals with the investigation of MIMO (multiple input multiple output) systems on a system level, including interference. The interference affects the capacity of each user and depends on the spatial characteristics of the propagation channel. It is spatially-colored. A necessary step towards a realistic performance evaluation is to include interference into the channel modelling process. A new multiuser double-directional channel model (MDDCM), that enables a correct interference description, is presented in this paper. It is based on a distributed scatterer approach and includes line-of-sight areas, far clusters and new models for street guided and over-rooftop propagation. Simulation results of a cellular multiuser MIMO system for the downlink case, based on the MDDCM, are presented. With this tool, it becomes possible to evaluate the performance of multiuser MIMO systems under realistic propagation and interference conditions. |
