In this paper, a novel joint design of beamforming and power allocation is proposed for a
multi-cell multiuser multiple-input multiple-output non-orthogonal multiple access network. In …

Serial interference cancellation (SIC) technology is the key to ensure a higher system
capacity for NOMA. However, SIC may also introduce some critical security risks, since it …

The integration of cognitive radio (CR) technology and non-orthogonal multiple access
(NOMA) techniques, referred to as CR-based NOMA systems, has been recently configured …

Owing to the superior performance in spectral efficiency, connectivity, and flexibility,
nonorthogonal multiple access (NOMA) is recognized as the promising access protocol and …

Contrary to orthogonal multiple-access (OMA), non-orthogonal multiple-access (NOMA)
schemes can serve a pool of users without exploiting the scarce frequency or time domain …
