This paper investigates the performance of cooperative non-orthogonal multiple access (C-
NOMA) in downlink communication systems. Using C-NOMA, users with more favorable …

Power allocation is an important issue in order to optimize the performance of non-
orthogonal multiple access (NOMA) systems. However, the power allocation problem for …

In conventional cooperative non-orthogonal multiple access (NOMA) networks, spectral
efficiency loss occurs due to a half-duplex constraint. To address this issue, we propose an …

This paper investigates the power allocation problem of full-duplex cooperative non-
orthogonal multiple access (FD-CNOMA) systems, in which the strong users relay data for …

This paper investigates the coexistence of non-orthogonal multiple access (NOMA) and full-
duplex (FD) to improve both spectral efficiency (SE) and user fairness. In such a scenario …

The full-duplex (FD) cooperative nonorthogonal multiple access (NOMA) achieves a
superior throughput over the conventional half-duplex (HD) cooperative NOMA, wherein the …

In this paper, we study the performance improvement methods for a cell-edge user of two-
user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end …

This paper studies a novel design of user pairing and resource allocation in a simultaneous
wireless information and power transfer (SWIPT)-enabled cooperative non-orthogonal …

We consider downlink non-orthogonal multiple access transmission where an access point
communicates with a set of near and far users via a full-duplex multiple antenna relay. To …

In this paper, the interplay between non-orthogonal multiple access (NOMA), device-to-
device (D2D) communication, full-duplex (FD) technology, and cooperation networks is …
