Description: 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.
