Upcoming multi antenna systems such as 3GPP- LTE employ code book based multi-mode precoding in order to adapt to a wide range of channel conditions. Link adaptation, which includes the selection of precoding matrices, the number of spatially multiplexed layers as well as modulation coding schemes is a crucial task, carried out by the receiver. In this contribution we propose link adaption based on the measure of mutual information between the channel input and the linear detector output and evaluate the behavior of the proposed algorithm in spatially correlated and uncorrelated propagation scenarios. The results highlight the importance of proper link adaption in order to mitigate the impact of spatial correlation.
