摘要 重叠传输模拟网络编码(ANC-OT)方案中,中继节点采用放大转发(AF)协议,不能避免噪声传播效应。针对此问题,提出了中继节点采用校验译码转发(DF)协议的重叠传输网络编码方案,中继节点根据其译码结果决定是否转发源节点的信号。理论分析表明所提方案的平均互信息和可靠性都优于ANC-OT方案,仿真结果验证了理论分析的正确性。 Amplify-and-forward protocol at relay node is adopted in Overlapped Transmission scheme for Analog Net-work Coding（ANC-OT）, and the propagation of measurement noises can’t be avoided. To solve this problem, overlapped transmission scheme for network coding with decode-and-forward protocol is proposed in this paper, in which whether to forward the source signals is determined by the decoding results at the relay node. Theoretical analysis shows that the pro-posed scheme outperforms ANC-OT in the average mutual information and reliability. Simulation results demonstrate the validity of the theoretical analysis.
