抄録

The application of compressed sensing (CS) based techniques to non-orthogonal multiple access (NOMA) systems has been investigated recently. In this paper, we propose a quality-of-service (QoS) aware low complexity CS-based user pairing and power allocation scheme for downlink NOMA systems, where the tolerable interference threshold is mathematically designed to achieve a given QoS requirement so that user pairing and power allocation problem is relaxed to l1 norm optimization problem under a QoS constraint based on the tolerable interference threshold. Simulation results show that the proposed scheme is effective in improving user rate compared with other reference schemes while the QoS requirement is approximately satisfied as long as the required QoS value is feasible.
