Abstract

In this paper, a transmission scheme of rate-split multiple access system in a power line communication channel is considered. The scheme consists of one sender and two users, and the signal for all users is superimposed at the sender. Using the continuous convex approximation method, we aim to maximize the total achievable rate of the system by optimizing the beamforming vector and rate allocation, and then propose a method based on continuous convex approximation to solve the optimization problem. The results show that, compared with PLC-NOMA, PLC-RSMA is suitable for various channel directions (whether the channel directions are aligned or orthogonal). PLC-RSMA can achieve better transmission rate performance, and with the increase of SNR, the rate performance gain of PLC-RSMA becomes more and more obvious. At the set parameters, when SNR is 30dB, the relative rate performance of PLC-RSMA is improved by at least 37% compared to PLC-NOMA.
