Non-Orthogonal Multiple Access (NOMA) is a prospective paradigm, which drastically
improves spectral efficiency by permitting several users to partake concurrently the same …

This paper proposes a cooperative nonorthogonal multiple access (CNOMA) scheme in a
full-duplex (FD) relaying cognitive radio network (CRN), where a primary user (PU) …

In this paper, we propose an overlay cognitive radio (CR) non-orthogonal multiple access
(NOMA) network to improve the performance of the primary receiver (PR) as well as the …

ABSTRACT Non-Orthogonal Multiple Access (NOMA) becomes a promising candidate for
future 5G due to its superior performances over orthogonal frequency division multiple …

This paper considers the application of non-orthogonal multiple access (NOMA) into
cooperative cognitive radio (CR) networks with simultaneous wireless information and …

In order to improve the performance of non-orthogonal multiple access (NOMA) system, a
downlink NOMA system with two symmetric users is investigated. By noting that the …

In this paper, we derive the throughput of non-orthogonal multiple access NOMA with
adaptive transmit power for cognitive radio networks (CRN). The secondary source and …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

The traditional orthogonal multiple access (OMA) is unable to satisfy the needs of large
number of smart devices. To increase the transmission rate in the limited spectrum resource …

In this paper, we propose a downlink cognitive non-orthogonal multiple access (NOMA)
network, where the secondary users (SUs) operate in underlay mode. In the network …
