在这封信中，我们设计了适用于多天线中继网络的非正交多址(NOMA)。假设移动用户的接收天线采用最大比合并(MRC)，而选择在中继处最大化瞬时信噪比(SNR)的发射天线。研究了系统的中断性能，给出了精确中断概率的闭合表达式。此外，我们还得到了中断概率的下界。最后给出了仿真结果，验证了理论分析的正确性和NOMA的优越性。
In this letter, we design non-orthogonal multiple access (NOMA) for multiple-antenna relaying networks. The receive antennas at the mobile users are assumed to adopt maximal ratio combining (MRC), whereas the transmit antenna that maximizes the instantaneous signal-to-noise ratio (SNR) at the relay is selected. The system outage performance is investigated and closed-form expressions for the exact outage probability are derived. Furthermore, we obtain the lower bound of the outage probability. Finally, simulation results are presented to show the correctness of the theoretical analysis and the superiority of NOMA.
