摘要：
Non-orthogonal multiple access (NOMA) technology allows multiple users to share the same spectrum resource. Meanwhile, the technology of spectrum sensing enables us to find the free time of the spectrum. Both two technologies can significantly improve spectrum efficiency. In this paper, we attempt to combine the two techniques, for meeting the higher demand of spectrum resources requirements in future communication. We propose a transceiver architecture by the combination of two techniques. And we verify the feasibility of this scheme. The experiments and obtained data reveal that the proposed method is feasible. And it manifests to have a good detection performance.
