Robust Linear Processing for Downlink Multiuser MIMO System With Imperfectly Known Channel
arXiv:0811.0413
Abstract
This paper proposes a roust downlink multiuser MIMO scheme that exploits the channel mean and antenna correlations to alleviate the performance penalty due to the mismatch between the true and estimated CSI.
