摘要

研究了无线携能传输协同中继非正交多址接入系统中的强用户速率最大化问题。通过把非凸的优化问题转化为凸优化问题

并由MATLAB仿真得到强用户速率的优化结果。结果表明: 此非正交多址接入系统的强用户速率随着源节点发射功率的增加而增加；在强用户速率性能方面

此非正交多址接入系统明显优于传统的时分多址接入系统。

Abstract

The maximization of the strong user rate in the cooperative relaying system using non-orthogonal multiple access (NOMA) system with wireless power transfer is studied. By transforming the non-convex optimization problem into the convex one

the optimization results of the strong user rate are obtained by MATLAB simulation. The results show that: 1) the strong user rate of this NOMA system increases with the increasing of the transmit power from the source node; 2) compared with traditional time-division multiple access (TDMA) system

the strong user rate performance of NOMA system obviously outperforms that of TDMA system.
