摘要 建立了基于置信传播(BP)算法的双向中继系统传输模型,理论推导了中继节点处物理层网络编码的映射关系,研究了不同调制方式下各种异步因素对通信系统误码率的影响规律,为无人机在实战中更广泛地应用提供理论基础。 The paper establishs two-way relay system transmission model based on belief propagauon (BP) al- gorithm, theoretically infers the mapping relationship of the relay node physical layer network coding, then in- fluence law of various asynchronous factors to communication system BER under different modulation is studied, the paper provides the theoretical basis for UAV's extensive use.
