Wireless Cooperative Transmission in Joint Tactical Communication Network

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.
