… considered to be imperfect. We investigate AF relaying in the cooperative CR NOMA network,
… By employing the worst model to model the imperfect CSI of the eavesdropper, we aim to …

… (NOMA) networks. However, traditional RA approaches have been proposed under perfect
channel state information (CSI) which … In this article, with imperfect CSI, a downlink robust RA …

… CR networks can be broadly categorized into three types based on the type of network they
operate in: i) Overlay CR Networks: Wherein the CR … ii) Interweave CR Networks: The CR …

… state information (CSI) imperfections on the NOMA performance are … imperfect CSI for a
generic cluster size. In [17], power-efficient resource allocation is studied for multicarrier NOMA …

… relevant works assume perfect CSI estimation. Effects of imperfect CSI on resource allocation
… Upon observation, we notice that the user rate is slightly lower for NOMA compared to OMA …

… In addition, the channel state information (CSI) is assumed to be perfectly known at the
transmitter similar to those works in Table 1. The cases with imperfect CSI are more challenging …

… , NOMA and CR scheme are considered as promising techniques to introduce new model
of CR-NOMA … We also evaluate worse case as imperfect CSI raised. We denote the transmit …

… (CCI) between CR networks and imperfect successive … NOMA (CRI-NOMA) paradigms
have received considerable attention from researchers when compared to underlay CR-NOMA …

… imperfect CSI and EH, so in this paper, we propose a robust power allocation for NOMA
heterogeneous networks with EH under imperfect CSI. … model of NOMA heterogeneous networks …
