    Optimization of a MIMO amplify-and- forward relay system with channel state information estimation error and feedback delay

    This paper addresses the robust design of a multiple-input multiple-output amplify-and-forward relay system against channel state information (CSI) mismatch due to estimation error and feedback delay. The esti...

    Optimization of a two-way MIMO amplify-and-forward relay network

    In this paper, we consider optimization of a two-way multiple-input multiple-output (MIMO) amplify-and-forward relay network which consists of a pair of transceivers and several relay nodes. Multiple antennas ...
