Point-to-point communication over flat-fading MIMO channels is considered. Known equalization and pre-equalization schemes are reviewed and compared. In particular, lattice-reduction-aided techniques are considered, and starting from them a new approach is derived. This proposed technique can be interpreted as a generalization of partial-response signaling, known from intersymbol-interference channels. The main advantage of this low-complexity scheme is that only very little channel-state information is required at the transmitter and performance close to maximum-likelihood detection is possible. Moreover, channel coding can directly be applied.
