摘要/Abstract

摘要： 为提升多向中继网络的频谱效率，提出一种基于协作复用的传输技术，多个配置单天线的中继节点对空间复用信号进行放大转发，接收节点收到足够数量的样本即可译码，减少了发送时间，提高了传输的有效性。针对三节点数据交互的情形，分析了该技术的频谱效率。结果表明，在高信噪比区域，相对于传统的和基于协作分集的传输方案，该技术的频谱效率分别提升了100%和200%。

Abstract: Cooperative multiplexing based transmission in N-way relay networks is proposed.Multiple relaying nodes equipped with single antenna amplify their received signals，which are spatial multiplexing.Receiving nodes can decode with enough observations and the efficiency is improved.The spectral efficiency is analyzed when three nodes communicate with one another via two relaying nodes.Simulation results show that at high SNR regimes，the cooperative multiplexing based transmission has higher spectral efficiency compared with the traditional and cooperative diversity strategies.

Key words: n-way relay, cooperative multiplexing, amplify-and-forward, spectral efficiency
