Low-Complexity Resource Allocation for Downlink Multicarrier NOMA Systems by Wang, Chin-Liang, Chen, Tzu-Ying, Chen, Yung-Fang, Wu, Dong-Shing

“… With such optimal power allocation factors for all subcarriers, a low-complexity suboptimal algorithm is then proposed for joint subcarrier and power allocation to meet the proportional user fairness constraint. Simulation results demonstrate that the proposed scheme provides better system capacity than the conventional orthogonal frequency division multiple access (OFDMA) scheme…”
