This paper investigates the application of non-orthogonal multiple access (NOMA) in a
coordinated direct and relay transmission (CDRT) system, where the base station (BS) …

In this paper, we carry out the performance analysis of the simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS) in the hybrid automatic repeat …

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 …

With the increasing requirements for efficient utilization of satellite resources, both non-
orthogonal multiple access (NOMA) scheme and cognitive radio (CR) have been recognized …

In this paper, the performance of non-orthogonal multiple access (NOMA) based cooperative
spectrum sharing in hybrid satellite-terrestrial networks (HSTNs) is investigated, where the …

Cooperative non-orthogonal multiple access (NOMA) assisted by a dedicated relay is an
effective way to improve the spectral efficiency and reliability of a cognitive radio network …

In this paper, the power allocation of Nonorthogonal multiple access (NOMA) for secondary
users (SU) in a Cognitive Mobile Radio Network (CMRN) is studied. In the proposed …

Non-orthogonal multiple access (NOMA) has been a strong candidate to support massive
connectivity in future wireless networks. In this regard, its implementation into cooperative …

Satellite communication has attracted great interests due to extensive coverage and no
terrain restriction, which can make up for the shortcomings of terrestrial communication …

In this paper, we consider an underlay cognitive hybridsatellite-terrestrial network (CHSTN)
which constitutes a primary satellite source communicating with its multiple terrestrial …
