Abstract

A transceiver structure for MIMO systems that comprises linear/non-linear precoding/decoding is optimized according to the MMSE criterion under the assumption that only long-term channel state information (or LT-CSI, i.e., fading channel and noise correlation matrices) is available at the transmitter. The structure generalizes different techniques known from the literature, such as BLAST, linear precoding and decoding and Tomlinson-Harashima precoding. Performance comparison of these known techniques and the proposed scheme, carried out by means of simulations, shows that relevant benefits can be obtained by taking advantage of LT-CSI at the transmitter.
