This study addressed the application of non-orthogonal multiple-access techniques (NOMA) to those satellite communications for which a significant imbalance in the link quality of user terminals can be expected. The SINR (Signal-to-Interference and Noise Ratio) imbalance can be mainly caused by the coexistence of different types of terminals, possibly with different antenna sizes, without excluding other reasons such as traffic asymmetry and relative location under the satellite beam radiation diagram. This link SINR asymmetry can be exploited to outperform the performance of orthogonal access schemes under different rate metrics, paying special attention to fairness in the service provision.
