Robust ARQ Precoder Optimization for AF MIMO Relay Systems with Channel Estimation Errors

In this paper, we consider the robust retransmission precoder design for amplify-and-forward (AF) multi-input multi-output (MIMO) relay systems with channel estimation errors. With the objective of minimizing the average mean-squared-error of symbol estimations, we propose a novel progressive retran...
