Cooperative non-orthogonal multiple access (C-NOMA) is one of the promising techniques
that support the massive connectivity of users and improve the fair allocation of network …

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

In this paper, we analyze the performance of an energy harvesting (EH)-assisted overlay
cognitive non-orthogonal multiple access (NOMA) system. The underlying system consists of …

In this paper, we study energy-efficient transmissions for multiple-input multiple-output
(MIMO) cognitive radio (CR) networks in which the secondary unlicensed users coexist with …

Combining energy harvesting with cognitive radio and nonorthogonal multiple access
(NOMA) techniques will be a notable candidate for improving both energy and spectral …

This paper studies the power allocation problem for a cognitive radio (CR) multiple-input-
multiple-output (MIMO) system under spectrum sharing with an existing primary radio …

Multi-carrier based non-orthogonal multiple access (NOMA) is an effective method to meet
the ever-increasing demands of both user throughput and energy efficiency by multiplexing …

This paper investigates the application of simultaneous wireless information and power
transfer (SWIPT) to nonorthogonal multiple access (NOMA). A new cooperative multiple …

Non-orthogonal multiple access (NOMA) has been recognized as a potential technique to
achieve higher spectral efficiency (SE) for future 5G systems. However, the anticipated …

In this paper, we propose a non-orthogonal multiple access (NOMA) relaying system, where
a source node communicates simultaneously with multiple users via the assistance of the …
