This paper studies the user selection problem for a cooperative nonorthogonal multiple
access (NOMA) system consisting of a base station, a far user, and N near users. The …

In this paper, we study the mode selection and subchannel allocation for the downlink of a
multi-user multi-subchannel cooperative non-orthogonal multiple access (C-NOMA) system …

In this paper, we derive the effect of channel errors on the performance of user relaying
cooperative NOMA system in closed-form. The max-min selection strategy is adapted to the …

This paper proposes a new communication protocol for a cooperative non-orthogonal
multiple access (NOMA) system. In this system, based on users' channel conditions, each …

Recently, non-orthogonal multiple access (NOMA) scheme is integrated with cooperative
communication (C-NOMA) to increase the connectivity and coverage area. In this paper, we …

In this paper, we investigate a downlink cooperative non-orthogonal multiple access
(NOMA) network with decode-and-forward relaying, where two scenarios of user relaying …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient technology to
satisfy the massive data requirement of the next-generation wireless communication …

This paper studies a two-user cooperative non-orthogonal multiple access network with a
novel cooperation scheme, where the source communicates with the near user directly or …

In this letter, we investigate the relay selection (RS) problem in cooperative non-orthogonal
multiple access networks, where one base station communicates with two paired users with …

Cooperative non-orthogonal multiple access (NOMA) systems inherit advantages of the
NOMA protocol and the cooperative relay. In this paper, we propose cooperative NOMA …
