中文摘要：
提出了一种新的物理层网络编码方法，将无线网络中物理层网络编码采用的调制方法推广到八进制相移键控（8PSK）以及多进制相移键控（MPSK）。该方法在中继节点采用星座映射，将MPSK和信号星座映射到MPSK信号星座。接收节点收到MPSK信号后进行解调，借助已有信息进行译码（异或）操作，得到对方节点信息，完成信息交换。仿真验证了该方法的有效性，与已有的物理层网络编码方法相比，该方法在中继节点节约了50％的能量消耗，进一步提高了信息传输速率。
英文摘要：
This paper presents a new physical-layer network coding （PNC） method, which extends the modulation method in PNC to 8 phase-shift keying （8PSK） and M-ary phase-shift keying （MPSK）. The method adopts constellation mapping in the relay node, and the constellation of MPSK sum-signals should be mapped into the original MPSK constellation. To obtain the other receiver＇s information and implement information exchange, each receiver demodulates the corresponding MPSK signal obtained and decodes （XOR） the bit information from the demodulator with its own. The simulation results show that the new method is effective, and compared with the original PNC method, this method can reduce 50% energy consumption in the relay node, and improve the information transmission rate.
