摘　　要：为了解决多用户通信场景中的数据与能量协作传输问题,针对采用链路自适应传输机制的协作通信网络,提出了一种基于多用户的数据与能量协作传输方法。建立链路连接关系;计算最大发射功率和中继节点到目的节点链路的发射功率和信噪比;根据信噪比和链路自适应传输机制,分别计算源节点到中继节点链路以及中继节点到目的节点链路的QAM调制阶数;根据计算出的两个QAM调制阶数,来确定中继链路的传输策略,从而实现优化系统通信性能。仿真结果证明了所提多用户数据与能量协作传输方法的有效性。In order to solve the problem of energy and data cooperative transmission in multi-user communication scenarios,a multi-user-based data and energy cooperative transmission method is proposed.The link connection relationship is established to calculate the maximum transmission power and the transmission power,as well as the signal-to-noise ratio of the relay node to the destination node link.According to the signal-to-noise ratio and link adaptive transmission mechanism,the QAM modulation order of the source node to the relay node link and the relay node to the destination node link is calculated respectively,the result of which determine the relay link transmission strategy based on the calculated two QAM modulation orders,therefore optimizing the communication performance of the system.The simulation results show the effectiveness of the proposed multi-user data and energy cooperative transmission method.
