摘要: 航空通信距离因地球曲率而受到限制，并行中继转发是解决远程航空通信问题的一种有效途径。传统的放大转发与检测转发能够延长通信距离，但中继节点之间相互独立，对于空间资源的利用并不充分。本文在并行中继转发结构的基础上，提出航空通信系统中的分布式空时码传输方案，利用虚拟的多天线系统实现中继节点的分布式空时编码，并提出对应的接收检测算法。仿真表明，所提方案能够大幅提高中继转发的可靠性。

Abstract: The distance of aeronautical communication is limited by the curvature of the earth. Parallel relay forwarding is an effective way to solve the problem of long distance communication. Traditional amplify-and-forward and detect-and-forward can extend the communication distance, but the relay nodes are independent with each other and the space resources are not fully utilized. Based on parallel relay forwarding architecture, we propose a distributed space-time coding transmission scheme in aeronautical communication, use virtual multi-antenna system to realize the distributed space-time coding at relay nodes, and propose the corresponding detection algorithm at the destination node. Simulation results show that the proposed scheme can improve the reliability of parallel relay system in aeronautical communication.
