报告摘要：

A receiver design problem for multi-access space-time block coded multiple-input multiple-output (MIMO) systems is considered. To hedge the mismatch between the true and the estimated channel state information (CSI), several robust receivers have been developed in the past decades. Among these receivers, the Gaussian robust receiver has been shown to be superior in performance. This receiver is designed based on the assumption that the CSI mismatch has Gaussian distribution. However, in real world applications, the assumption of Guassianity might not hold. Motivated by this fact, a more general distributionally robust receiver is proposed, where only the mean and the variance of the CSI mismatch distribution are required in the receiver design. A tractable semi-definite programming (SDP) reformulation of the robust receiver design is developed.
