摘要 研究表明增量中继技术既能够使无线协作网络达到较高的分集增益,同时也可以提高系统资源(频谱,功率等)的利用率。文中研究了一个多输入多输出(Multi-input Multi-out-put,MIMO)中继信道,包含1个信源,1个中继以及1个信宿,所有节点均为多天线。中继节点为半双工工作模式,且采取增量中继技术。仿真结果表明其在性能上优于原有方法。 It has been shown that incremental-relay technique can improve both the diversity gain and energy-efficiency in wireless cooperative networks. This paper considers a multiple-in multiple-out relay channel with 1 sources, 1 relays and 1 destination, where all nodes are of multiple antennas. Half- duplexing relay performs Incremental-relay technique. The simulation results show that the proposed scheme outperforms the existing schemes.
