In this letter, we study linear pre-equalization in conjunction with BLAST equalization. Linear pre-equalization is based on the assumption that the channel state information available at the transmitter is limited to the second order statistics of channel and noise (long term channel state information or LT-CSI). Through simulations, we compare different design criteria for the pre-equalizer and show the advantages of the considered structure with respect to BLAST.
