… imperfect CSI non-robust design, we provide a new understanding of IRS-aided OMA and
IRS-aided NOMA … We first drive the rates of each user in the NOMA communication system. …

… -NOMA users are derived theoretically under both perfect and imperfect CSI. The SMBM-…
of the proposed SMBMNOMA system under the perfect and imperfect CSI is analyzed and …

… We can see that P 1 is non-convex due to rate constraints which contain interference due
to NOMA users, co-channel, and imperfect CSI. Moreover, the formulated problem is coupled …

… Different conventional orthogonal MA, NOMA can serve multiple users … NOMA enhances
spectral efficiency by squeezing a near user (NU) into the spectrum occupied by a far user (FU). …
