Joint Optimization of Transceiver Matrices for MIMO-Aided Multiuser AF Relay Networks: Improving the QoS in the Presence of CSI
—This paper addresses the problem of amplify-6 and-forward (AF) relaying for multiple-input–multiple-output7 (MIMO) multiuser relay networks, where each source transmits8 multiple data streams to its corresponding destination with the9 assistance of multiple relays. Assuming realistic imperfect chan-10 nel state information (CSI) of all the source–relay and relay–11 destination links, we propose a robust optimization framework12 for the joint design of the source transmit precoders (TPCs),13 relay AF matrices and receive filters. Specifically, two well–14 known CSI error models are considered, namely, the statistical15 and the norm-bounded error models. We commence by consid-16 ering the problem of minimizing the maximum per-stream mean17 square error (MSE) subject to the source and relay power con-18 straints (min–max problem). Then, the statistically robust and19 worst-case robust versions of this problem, which take into ac-20 count the statistical and norm-bounded CSI...
