摘　　要：正交幅度调制(QAM)是物理层网络编码中一种重要的调制方式,文章介绍了ARB三节点模型中物理层网络编码中继映射准则,分析了QAM调制方式下中继的误码性能,得出了物理层网络编码在节省通信时隙之外所获得的"编码增益"。另外文章对ARB模型中发送节点功率分配问题进行了考虑,通过分析,进一步说明了物理层网络编码的可行性,最后文章探讨了下一步物理层网络编码中继映射准则可能的发展方向。QAM is an important modulation method of Physical-layer Network Coding （PNC）. The mapping rules of PNC in ARB network model were introduced. The BER performance of QAM was analyzed and some benefit was got of PNC besides the decrease of the communication time-slots. The power allocation of the transmitters was considered showing that the PNC is viable. Finally, further research on PNC mapping rules of relay was discussed.
