“…In the scenarios where uplink NOMA is profitably employed, such approximation is verified, i.e., the spacing is sufficiently wide; as a matter of fact, this is the condition that allows to better discriminate among simultaneously received signals. Given this assumption holds, observe that it is possible to leverage upon a further approximation, namely, (2) (•) that appears in (23) is replaced by 2 (•), the CDF of the unordered random variable 2 . This leads to…”

“…Due to the complex nature of the analysis, the authors exclusively considered the circumstance of two superimposed users for mathematical tractability. In [23], the channel model was the generalized -fading and, also in this work, the SIC decoding order was fixed; here too, the analysis was limited to the circumstance of two or at the most three simultaneously active users.…”

“…To perform a similar operation, the authors in [22], [23] have applied the relay technique to enhance weak user performance. Regarding a performance analysis for downlink nonorthogonal multiple accesses (DL-NOMA) systems where the channel gains follow the 𝛼 − 𝜇fading distribution in [24], [25]. The authors considered bit error rate (BER), and ergodic capacity (EC).…”

“…The outage analysis and sum rate is presented in Sharma et al, 29 considering diversity combining techniques such as MRC, equal gain combining (EGC), and selection combining (SC) over ημ fading for a multiuser DL‐NOMA system. The outage performance, BER, and ergodic capacity of the NOMA system are investigated in Alqahtani et al 30 over the generalized αμ fading distribution.…”
