| Abstract(in English) | In this paper, we propose a quality-of-service (QoS)-aware low complexity compressed sensing (CS)-based user selection and power allocation scheme for downlink non-orthogonal multiple access (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 selection 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 improve the achieved data rate while meeting QoS requirement as far as it is feasible. |
