| Abstract(in English) | Downlink non-orthogonal multiple access (NOMA) systems with successive interference cancellation requires an effective user paring strategy that assigns proper user-pair to the same resource block. In this paper, we propose a quality-of-service (QoS)-aware low complexity compressed sensing (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. Based on the fact that selecting a user-pair among all users is treated as a `sparse' situation, joint user pairing and power allocation problem is relaxed to $l1$ norm optimization problem under a QoS constraint based on the tolerable interference threshold, which can be solved by general CS algorithm. 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. |
