Non-orthogonal multiple access (NOMA) is being widely considered as apotential candidate to enhance the spectrum utilization in beyond fifth-generation (B5G) communications . In contrast to the existing CRS-NomA systems, the system withreceive diversity outperforms its orthogonal (OMA-based) basedpart even in the low-SNR regime, by achieving higher ergodic rate . We also discuss theproblem of optimal power allocation for the minimization of the outageprobability of the system, and subsequently use this optimal value to obtain the ergodIC rate . An excellent match is observed between the numerical and theanalytical results, confirming the correctness of the results, confirms the accuracy of the derived analytical results, according to the results . We conclude that the system achieves full diversity order using both SC and MRC schemes, and this diversity order depends on both the shape
