“…However, these studies did not delve into the specific performance metrics of NOMA systems. In contrast, reference [17] proposes an adaptive power allocation technique based on fuzzy logic (FL) to improve system performance by analyzing user rate fairness and system interruption probability, while references [18][19][20][21][22] provide a comprehensive analysis of several performance metrics, including fault probabilities, security, and data transmission rates, and ensure system security and speed. In particular, reference [23] discusses the interruption probability and diversity order of cooperative NOMA schemes and finds that they can enhance system stability.…”

In collaborative combat operations, the challenges posed by communication adversities in aviation data links have become increasingly conspicuous. Ensuring the reliable connectivity of data links has thus emerged as a critical issue, particularly in light of growing interference effects on communication link outage. To address this challenge, this paper proposes a cooperative non-orthogonal multiple access (NOMA) technology that aims to enhance interference tolerance and strengthen stable communication capabilities in data links. To achieve these goals, an anti-interference collaborative NOMA system model applicable to aviation data links is established, and the anti-interference performance of collaborative NOMA technology is analyzed under Rice fading channel conditions. The analysis centers on the system’s outage probability, for which a closed-form expression is derived. Numerical analysis methods are employed to calculate and solve the expression, while simulation experiments are conducted to analyze the effect of factors such as transmission power, cooperative forwarding power, interference power, communication distance, and allocation coefficients on the system’s outage probability. The results show that the aviation data link system using a collaborative NOMA scheme has better anti-interference performance than a non-collaborative scheme, and adjusting the above parameters can effectively improve the system’s stable communication performance.

“…A hybrid NOMA proposed in [3] clusters users in small path loss (strong) and large path loss (weak) groups. In [4], sum rate and outage expressions of hybrid NOMA schemes namely, hybrid NOMA-OMA, NOMA Space shift keying (NOMA-SSK) and Successive user relaying cooperative NOMA (SR-NOMA) are derived. The authors observe better performance with NOMA-SSK compared to the other discussed schemes.…”

The application of multiple-input multiple-output (MIMO) on power domain sparse code multiple access (PD-SCMA) systems would enhance their performance by increasing the multiplexing and diversity gains. However, this is at a cost of increased detection complexity, as more users and antennas are deployed. This work develops and investigates the performance of spatial multiplexing MIMO based hybrid PD-SCMA system (M-PD-SCMA) transceiver on an uplink heterogeneous network over Rayleigh flatfading channels. The aim is to strike a balance on the number of antennas and capacity/spectral efficiency. The system capacity and outage robustness of the proposed transceiver in imperfect channels is evaluated and the bit error rate (BER) performance analysed. The link-level simulation results demonstrate that M-PD-SCMA achieves performance benchmark with PD-SCMA schemes. The proposed receiver achieves guaranteed BER performance with an increase in the number of transmit and receive antennas. Besides, the results highlight the impact of the codebook size, number of layers and power level distinctiveness on the outage bounds at each receive antenna at different SNR levels. Thus, the feasibility of an M-PD-SCMA system is validated.
