Cognitive radio non-orthogonal multiple access (CR-NOMA) technique can enhance the
perception of whole resources by combining cognitive radio and non-orthogonal multiple …

The non-orthogonal multiple access (NOMA) scheme realizes the transmission of multiple
user signals at the same time and frequency resource block through power domain …

This paper investigates the impact of relay selection on cognitive radio non-orthogonal
multiple access (CR-NOMA) based satellite-ground cooperation network. By analyzing the …

Abstract Non-Orthogonal Multiple Access (NOMA) is one of the key candidate technologies
for 5G networks. Combined with Cognitive Radio (CR) technology, the CR-NOMA system …

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 …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

This letter studies the application of non-orthogonal multiple access to a downlink cognitive
radio (termed CR-NOMA) system. A new cooperative transmission scheme is proposed …

In this paper, we study a cooperative non-orthogonal multiple access (NOMA) system
underlying cognitive networks which adapt user relaying and selection combining. The …

In this letter, we investigate the performance of an overlay cognitive satellite-terrestrial
network comprising a primary satellite source with its multiple terrestrial receivers and a …

This paper investigates the joint relay and antenna selection strategy for amplify-and-
forward (AF) cognitive radio-inspired non-orthogonal multiple access (CR-NOMA) systems …
