… In this section, we derive the outage probability expression for both NOMA users. Outage
probability gives the achievable maximum rate for error-free transmission [32]. The closed-form …

… Then, energy efficiency of users in the NOMA UAV network with imperfect CSI is discussed
… paper, imperfect CSI especially as small scale fading between hovering UAVs and users is …

… • In this article, we consider a multi-user multi-BS NOMAMEC network with imperfect CSI.
We aim to minimize the energy consumption of the offloading and computation processes by …

… In addition, we can find that the sum throughput of NOMA users decreases as the level of
residual interference increases in low SNR region, and the sum throughput of perfect SIC and …

… In this paper, we investigate a multiple users cooperative overlay … -NOMA system in the
presence of imperfect SIC and CSI is considered to improve the performance of cell-edge users. …

… in the case of imperfect CSI caused by the channel estimation error. The result shows that
the system performance is reduced significantly due to the imperfect CSI. All analysis results …

… obtain exact CSI due to … Imperfect CSI: Since it is difficult to obtain perfect CSI due to
quantization errors and parametric estimation errors, robust RA schemes with imperfect CSI in NOMA…

… the outage probability of a two-user CNOMA system under imperfect CSI. Compared to [21] …
systems with imperfect CSI proposed in [21] to multiple users scenarios, and discuss the user …

… We study the throughput and energy efficiency for two users in delay-limited transmission
mode of NOMA-MEC system and derive the corresponding expressions. We find that …

… 1, we consider an underlay FDNOMA-based CRNs with imperfect CSI, which … user (SU)
transmitter (BS), a pair of SU receiver (strong user Ua and weak user Ub), one primary user …
