Abstract

We present multiple antenna transmitter optimization (i.e., spatial prefiltering) 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 the maximum achievable data rates in the case of the zero-forcing and triangularization spatial prefiltering coupled with a dirty paper coding transmission scheme. We also present the effects of channel mismatch.
