| 摘 要： | 为提升网络能效性能，本文构建了NOMA-SWIPT协作中继网络模型，并采用了一种基于黄金分割(Golden Section, GS)的DinkelBach迭代算法来解决能效优化问题。仿真结果表明，GS-DinkelBach算法在获得精准的能效增益的同时，具有更低的计算复杂度；与传统直连网络模型和中继转发网络模型相比，本文建立的网络模型的最优能效值分别提升了1.07 dB和2.17 dB。

| Abstract: | In order to improve the energy efficiency performance of cooperative networks, a NOMA-SWIPT cooperative relay network is constructed in this paper and a DinkelBach iterative algorithm based on the Golden Section (GS) is proposed to solve the energy efficiency optimization problem. The simulation results show that the GS-DinkelBach algorithm can obtain precise energy efficiency gains with lower computational complexity. Compared with the traditional direct-link network model and the relay network model, the optimal energy efficiency of the established network model could be increased by 1.07 dB and 2.17 dB, respectively. |
