Multiple-input multiple-output (MIMO) channels provide an abstract and unified
representation of different physical communication systems, ranging from multi-antenna …

In practical wireless systems, the design of linear MIMO transceivers should be robust to
imperfect channel state information (CSI), especially in multiuser systems where accurate …

In this paper, we investigate the robust transceiver design for dual-hop amplify-and-forward
(AF) MIMO relay systems with Gaussian distributed channel estimation errors. Aiming at …
