Abstract

In this paper we propose a novel method for joint transmit-receive linear optimization in the downlink of a multiuser MIMO communication system. This new method adapts existing joint linear optimization algorithms from the single user domain for application to the multiuser domain. The optimum transmit matrix is obtained using an iterative procedure based on a minimum mean-squared error (MMSE) criterion and a per-user power constraint; the optimum receive matrices for each user are then derived under an MMSE constraint. The proposed technique improves performance and increases data throughput in multiuser scenarios.
