| 摘 要： | 该文提出了一种基于网络编码和空时协作的增强型双向中继方案。根据系统各节点的反馈，该方案将网络编码和空时协作有机结合，能提高系统资源利用率和网络吞吐量。推导了所提方案及现有的两种双向中继方案的中断概率，并分析了各方案在快衰落和慢衰落信道下的分集增益和网络编码增益。结果表明：相对于其它两种方案，所提方案在快衰落信道下，可获得三阶的分集增益；在慢衰落信道下，也可获得更高的编码增益。最后通过仿真验证了分析结果的正确性。

| Abstract: | An Incremental Coded Bi-directional Relaying (ICBR) scheme based on network coding and space-time cooperation is proposed, which utilizes the feedback information from nodes in the system. Cooperation in this way could improve resource efficiency and network throughput. The outage probabilities and the network-coding gain of different bi-directional relaying schemes are developed and analyzed. The numerical results show that compared with the other two schemes, ICBR scheme brings three-order diversity gain in fast fading channels and higher coding gain in slow fading channels. Furthermore, the theoretical results are verified with the simulation results. |
