| 摘 要： | 对协作分集进行简单介绍,提出了将协作分集应用到散射通信中的方案,分析了协作分集在散射通信中的应用可行性。并对其中的放大转发和译码转发在只有一个中继节点的情况下进行仿真,仿真结果证明在大信噪比时译码转发的性能优于放大转发。且协作分集应用到散射通信中在相同的信噪比下,误码率更低,提高了系统性能。利用协作分集技术对散射通信进行组网,较直接组网设备复杂度低,易于实现。

| Abstract: | A brief introduction of cooperation diversity is given.A new method that applies cooperation diversity to troposcatter communication is proposed,and its feasibility is analyzed.Amplify and Forward(AF),Decode and Forward(DF)with one relay node are simulated.The simulation result proves that communication system with DF has better performance than AF with large Signal to Noise(SNR)and the application of cooperation diversity in troposcatter communication have lower bit error rate(BER)with the same SNR,improving system performance.The application of cooperation diversity in troposcatter networking has lower complexity and can be easily realized. |
