… 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 …

… CONCLUSION In this paper, we investigated the power allocation problem for NOMA based
on the outage probability with imperfect CSI. We first derived closed-form expressions for …

… NOMA highly depends on the quality of CSI. In this paper, we investigate the effect of imperfect
CSI in an EH-NOMA … a cooperative NOMA network, consisting of a source, two users, and …

… 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)
