摘要：
In this paper, we extend a jointly optimized linear prefilter and nonlinear vector perturbation approach to the MIMO multiuser (MU) precoder system where each user has multiple antennas. As a prefilter design, we use the weighted MMSE criterion. Based on the best weighting condition, we propose a recursive MMSE prefilter.
