Abstract

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.

Key words: non-orthogonal multiple access (NOMA), wireless power transfer, rate optimization, power allocation, power splitting ratio
