In this paper we present multiple antenna transmitter optimization (i.e., spatial pre-filtering) schemes that are based on linear transformations and transmit power optimization (keeping average transmit power conserved). We consider the downlink of a wireless system with multiple transmit antennas at the base station and a number of mobile terminals (i.e., users) each with a single receive antenna. We consider maximum achievable data rates in the case of the zero-forcing and triangularization spatial pre-filtering coupled with dirty paper coding transmission scheme. We also present the effects of channel mismatch.
