Abstract

This paper develops new algorithms for linear transceiver design for multiuser MIMO systems. Based on MSE duality, we derive new algorithms for the problem of min-max relative layer-MSE (the ratio of the layer-MSE to the given requirement) and the problem of layer-MSB constrained power minimization. The proposed algorithms differ from the previous work in the way that the layer-MSE is handled directly, therefore different requirements for different data streams (layers) are possible for the min-max problem. Furthermore, the algorithms have very low complexity and are proved to be convergent. The proposed schemes do not impose any restrictions on the number of antennas.
