[SMS] CAMSAM_05_TUI DL : 0: If SDMA is used on the downlink of a multi-user MIMO system, either long-term or short-term channel state information has to be available at the base station (BS) to faciliate the joint precoding of the signals intended for the different users. Precoding is used to efficiently eliminate or suppressmulti-user interference (MUI) via beamforming or by using ”dirty-paper” codes. It also allows us to performmost of the complex processing at the BS which leads to a simplification of the mobile terminals. In this paper, we provide an overview of efficient linear and non-linear precoding techniques formulti-userMIMO systems. The performance of these techniques is assessed via simulations on statistical channelmodels, and on channels generated by the IlmProp, a geometry-based channel model that generates realistic correlations in space, time, and frequency.
