Subcarrier, power, and rate allocation schemes for the orthogonal frequency division multiple access (OFDMA) uplink are considered. A low-complexity algorithm with fairness consideration is proposed ...

This paper investigates the joint subcarrier and power allocation problem for the downlink of a multi-carrier non-orthogonal multiple access (MC-NOMA) system. A novel three-step resource allocation ...
