| 摘 要： | 针对单中继非再生放大转发(AF)的进近飞行器协同传输网络,在给出系统模型后,推导并分析了系统的输出信噪比(SNR)表达式,得到了中继节点参与协同传输的条件,提出了一种自适应的协同传输方案.目的节点判断是否采用中继传输并将结果发送到中继节点,中继节点根据接收到的信息调整传输模式.在此基础上,针对多节点正交性协同传输会显著...

| Abstract: | This paper presents a study of the non-regenerative amplify-and-forward(AF) aircraft cooperative relay transmission network.The model of a single relay cooperative transmission system is given,and the expression of the output signal-to-noise ratio(SNR) is derived and analyzed.After that,the cooperative transmission condition of the relay node is acquired.Then an efficient adaptive cooperative transmission scheme is proposed.First,the destination node determines whether or not relaying should be adopted and ... |
