摘要
为提升网络能效性能,构建了非正交多址接入(non-orthogonal multiple access,NOMA)-无线携能通信(simultaneous wireless information and power transfer,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,所建立网络模型的最优能效值分别提升了1.07 dB和2.17 dB。
In order to improve the energy efficiency performance of cooperative networks,a non-orthogonal multiple access-simultaneous wireless information and power transfer(NOMA-SWIPT)cooperative relay network was constructed and a DinkelBach iterative algorithm based on the golden section(GS)was 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.
