… ) of two NOMA secondary destination users (U 1 and U 2 ) are derived in the case of imperfect
… Moreover, the proposed system model shows the superiority of the CR-NOMA compared …

… OUR CONTRIBUTION It is worth pointing out that few papers studied CR-assisted NOMA-V2X.
In fact, problem of performance improvement for vehicles in the secondary network (SN) …

… imperfect SIC and CSI has not been analyzed yet. However, imperfect SIC and CSI effects
limit the performance of NOMA … CR-NOMA system in the presence of imperfect SIC and CSI is …

… imperfect CSI was considered, this paper investigates the OP of a generalized and imperfect
CR-NOMA… hardware impairments (HIs), CSI imperfections, and residual interference caused …

… Moreover, in V2X it is critical to inspect imperfect channel state information (CSI) because, …
, CR based approach which is supported by NOMA with imperfect CSI, called as B-CR-NOMA …

… Furthermore, to improve the transmission reliability, the PLS of CR NOMA networks with
full-duplex (FD) operation based cooperative jamming scheme have been widely studied [9]–[11]…

… To address these challenges, we propose the CR-NOMA under a scenario of imperfect
CSI by considering the Nakagami-m fading channel model. The proposed system in this …

… NOMA mode was used in the previous works. According to the author’s knowledge,
underlay CRNOMA-based D2D communication under imperfect CSI … , the underlay CR-NOMA-based …

… NOMA. Motivated by [19], this paper studied CR-NOMA with imperfect CSI, but we emphasize
on system performance analysis by exploiting a distribution of Rician fading channel. …
