摘　　要：针对联合战术通信网络拓扑变化导致的通信中断风险,研究了基于物理层的无线协同传输技术。基于典型场景建立了MIMO协同和多跳中继协同模型;分析了模型中的信道容量及信噪比等指标;为验证分析结论设计了仿真实验,进行不同收发配置、编码、跳数情况下的对比。给出了两类协同收发机结构并分析了其硬件实现复杂度。理论分析及仿真实验结果均证明了无线协同传输技术在降低网络中断风险的有效性和可实现性。The wireless simultaneous interpreting technology based on physical layer is investigated to address the risk of communication disruption caused by topological changes of tactical communication networks.First,MIMO cooperation and multi-hop relay cooperation models are established based on typical scenarios.Second,the channel capacity and signal-to-noise ratio of the model are analyzed.To verify the findings,an experiment is designed,and the results under different transceiver configurations,codings,and hops are compared.Finally,the structures of two kinds of cooperative transceivers are described and their hardware implementation complexity analyzed.Theoretical analysis and simulation experiments have proved the effectiveness and feasibility of the wireless simultaneous interpreting technology in reducing the risk of network outages.
