摘　　要：为了推导计算MIMO-PNC中继系统信道容量,对几种中继方案进行了简要介绍,列出了各中继方案的信道容量,并详细阐述了物理层网络编码技术(Physical-layer Network Coding,PNC)放大转发中继的信道容量。在PNC放大转发中继系统基础上,引入多天线技术(Multiple-Input Multiple-Output,MIMO)技术,并推导出MIMO-PNC中继系统的信道容量。对几种中继方案进行了仿真,MIMO-PNC双向中继系统具有明显优越性,仿真结果表明,天线个数越多MIMO-PNC中继系统的信道容量越大,且在较低信噪比就超越了其他双向中继系统。Based on the two-way relay system, this paper focuses on the channel capacity of MIMO-PNC system. Several relay schemes and their channel capacity are briefly introduced,but the throughput of the PNC amplify-forward relay system is described in detail.With MIMO technique,the MIMO-PNC relay system is built upon PNC relay scheme,and the channel capacity is obtained for MIMO-PNC relay system. The simulation is performed for several relay schemes. The MIMO-PNC relay system has an obvious superiority.The simulation results show that the more antennas MIMO-PNC relay system has,the larger channel capacity is achieved, and the MIMO-PNC relay system exceeds other relay schemes at lower SNR.
