Energy harvesting with cognitive radio and nonorthogonal multiple access (NOMA)
techniques offer a promising solution to enhance the spectral and energy efficiency in …

In this paper, we analyze the performance of an energy harvesting (EH)-assisted overlay
cognitive non-orthogonal multiple access (NOMA) system. The underlying system consists of …

In this paper, we investigate a multiple users cooperative overlay cognitive radio non-
orthogonal multiple access (CR-NOMA) network in the presence of imperfect successive …

This paper investigates the performance analysis of cognitive-inspired wireless-powered
non-orthogonal multiple access (NOMA) systems, where two collaborative schemes are …

In this paper, we investigate the effectiveness of an overlay cognitive radio (OCR) coupled
with non-orthogonal multiple access (NOMA) system using a full-duplex (FD) cooperative …

We study the outage probability performance of hybrid protocols in relay-assisted, non-
orthogonal multiple access (NOMA)-based power line communication. In particular, we …

In this paper, we investigate a decode-and-forward relay-assisted cooperative non-
orthogonal multiple access (NOMA) scheme, where the relay implements a time-switching …

This letter investigates an overlay cognitive Alamouti's space-time block code-aided non-
orthogonal multiple access (STBC-NOMA) system. Approximate closed-form expressions for …

In cognitive radio networks (CRNs), the performance of the primary users (PUs) may suffer
adverse effects from the secondary users (SUs) if the spectrum of PUs is haphazardly …

In this paper, we consider a novel cooperative underlay cognitive radio network based on
non-orthogonal multiple access (CR-NOMA) with adaptive relay selection and power …
