The paper develops optimal and suboptimal resource allocation schemes for full-duplex multicarrier non-orthogonal multiple access (FD MC-NOMA) systems, demonstrating substantial improvements in system throughput and user fairness over traditional FD MC-OMA and half-duplex NOMA, with up to 49% higher throughput than FD MC-OMA.
Key insights
- The integration of full-duplex communication with multicarrier non-orthogonal multiple access (FD MC-NOMA) provides substantially higher spectral efficiency and better fairness compared to FD MC-OMA and HD NOMA by exploiting both frequency and power domain multiplexing.
- While the optimal solution provides a performance benchmark, the proposed suboptimal successive convex approximation (SCA) algorithm achieves near-optimal performance with significantly reduced computational complexity, making it practical for real-world implementation.
- Effective self-interference (SI) cancellation at the full-duplex base station is critical for FD MC-NOMA systems, as performance gains diminish rapidly with increased residual SI, particularly beyond a -110 dB cancellation constant.
