… research works on NOMA systems assume perfect channel state information (CSI). However…
for a downlink NOMA single-cell network by considering imperfect CSI. The energy efficient …

… 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 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 …

… Our problem formulation in this work is to maximize EE using optimum user power allocation
with imperfect CSI. The channel estimation error makes Rk a non-concave function with …

… • 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 …

… imperfect CSI on the outage probability of downlink two-user CNOMA networks in which the
near user acts as a DF relay for assisting the far user. For two different types of imperfect CSI …

… 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 …

… outperform the OMA users for all SNR regimes in no ITC case. When I = 25 dB, the OP curves
for NOMA users start to saturate at lower SNR regimes compared to those of the OMA users…

… In this paper, we consider the outage constrained sum utility optimization in MIMO-NOMA
systems under imperfect CSI available at the BS and users. Considering the computational …

… 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. …
