Wireless-Powered Communications With Non-Orthogonal Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2016 We study a wireless-powered uplink communication system with non-orthogonal multiple access (NOMA), consisting of one base station and multiple energy harvesting users. More specifically, we focus on the individual data rate optimization and fairness improvement and we show that the formulated problems can be optimally and efficiently solved by either ...

On Non-Orthogonal Multiple Access in Downlink
CoRR, 2016 Non orthogonal multiple access (NOMA) in the downlink is discussed in this letter. When combined with soft frequency reuse, NOMA is detrimental to user fairness by increasing the data rate of a near user at the cost of data rate of a far user.

Cooperative Non-Orthogonal Multiple Access in Cognitive Radio [PDF]
IEEE Communications Letters, 2016 This letter studies the application of non-orthogonal multiple access to a downlink cognitive radio (termed CR-NOMA) system. A new cooperative transmission scheme is proposed aimed at exploiting the inherent spatial diversity offered by the CR-NOMA system. The closed-form analytical results are developed to show that the cooperative transmission scheme
