Beyond Nonorthogonal Multiple Access: New Role of Constructive Interference

In this letter, we introduce a novel framework of constructive non-orthogonal multiple access (NOMA) transmission, which provides the merit interference utilization and breaks through (CI)’s limitation on multiuser (MU) capability. With dedicated synthetic successive coding hybrid MU designs, NOMA (CNOMA) precoder is proposed, particularly suitable for scenario where users have heterogeneous throughput requirements. Explicitly, it makes composite always beneficial to having high requirement, while accommodating another sets under their subscribed reception-quality requirement. Finally, number fundamental properties CNOMA design revealed, such as tradeoff between improvement Simulation demonstrates that proposed significantly outperforms classic CI minimum-mean-square-error precoders in performance, meanwhile obtains capability close designs.
