摘要

针对一种双跳多输入多输出(MIMO)放大转发(AF)多中继系统，提出了源/中继-预编码器和目的-均衡器组合优化方法。在考虑相关信道不确定性的基础上，基于最小均方误差(MMSE)准则设计了一种鲁棒的收发器接头设计。仿真结果表明，多中继AF-MIMO系统的鲁棒收发器设计体系结构大大优于非鲁棒收发器设计。

Joint optimization for MIMO AF multiple-relay systems with correlated channel uncertainties

In the paper, the source/relays-precoders and destination-equalizer combined optimization is proposed in a dual-hop multiple-input multiple-output (MIMO) amplify-and-forward (AF) multiple-relay system with correlated channel uncertainties in both hops. By taking correlated channel uncertainties into account, a robust transceiver joint design is developed based on the minimum mean-squared error (MMSE) criterion under individual power constraints at the source and relays. Simulation results illustrate that the robust transceiver design architecture for an AF-MIMO system equipped with multiple relays outperforms substantially the non-robust transceiver design.
