| 摘 要： | 网络编码理论提高了数据的传输效率,而物理层网络编码进一步缩短了数据交互的时隙,它认为:只要中继节点R采取了恰当的调制解调技术,可以使电磁信号的叠加映射到数字域上的运算操作,实现两时隙交互信息。可见选择恰当的调制解调技术对实现物理层网络编码至关重要。该文从调制技术这一角度出发,综合目前在物理层网络编码中所应用的调制解调技术,对其进行分析总结,并展望了下一步物理层网络编码中调制技术的发展。 |

| Abstract: | Network coding theory enhances the transmission efficiency,and Physical-Layer Network Coding （PNC） can reduce the transmission time-slots of inter-communication.It assumes that through a proper modulation-and-demodulation technique at the relay node,additions of EM signals could be mapped to GF （2n） additions of digital bit streams and time-slots reduce to two.The paper shows that the proper modula- tion-and-demodulation technique is significant to PNC realization.The paper introduces and compares the modulation techniques used in PNC briefly.The modulations for PNC open many possibilities for further re- search. |
