TL;DR: This letter addresses the sum-rate maximization for a downlink non-orthogonal multiple access (NOMA) system in the presence of imperfect successive interference cancellation (SIC), and optimize the circularity coefficient of the IGS-based NOMA system to maximize its sum- rate subject to quality-of-service requirements.

TL;DR: Numerical results illustrate the robustness of QSM in enhancing the overall system performance in the presence of estimation errors, as well as insights on the system diversity and channel estimation errors’ effects.

TL;DR: This work addresses the energy efficiency maximization for a downlink cooperative full-duplex non-orthogonal multiple access (FD-NOMA) system in the presence of imperfect self-interference cancellation and jointly optimize the power allocation at the base-station and the IGS circularity coefficients of the cooperative IGS-based FD- NOMA system to maximize its energy efficiency subject to quality-of-service (QoS) requirements.

TL;DR: Simulation results show the importance of QSM in improving the overall secondary performance and a closed-form expression for the average pair-wise error probability of the secondary system is derived and used to calculate a tight upper bound of the average bit error rate (ABER) over Rayleigh fading.

TL;DR: A new analytical expression for the Pairwise Error Probability (PEP) over selective frequency Rayleigh fading channel is derived and is used to calculate a tight upper bound of the Average Bit Error Probable (ABEP).
