Non-orthogonal multiple access (NOMA) is a better multiple access technique than
orthogonal multiple access (OMA), precisely orthogonal frequency division multiple access …

We propose a new signal spreading-based non-orthogonal multiple access (NOMA)
schemes that exploits the frame-theoretic design principles to enable the efficient …

Non-orthogonal multiple access (NOMA) is widely recognized to increase the number of
users and enhance the spectral efficiency in fifth-generation (5G) wireless networks and …

Non-orthogonal multiple access techniques have been proposed recently for 5G wireless
systems and beyond to improve access efficiency by allowing many users to share the same …

We investigate the performance of a hybrid non-orthogonal multiple access (NOMA) multi-
cell downlink system (called hybrid as different users can have different successive …

The fifth generation (5G) wireless systems are anticipated to meet unprecedented capacity
and latency requirements. In order to resolve these challenges in 5G, non-orthogonal …

-Non-orthogonal multiple access (NOMA) is a spectrum reutilization technique that
superposes messages in the power domain allowing multiple users to be served in the …

This paper investigates several new strategies for the allocation of radio resources
(bandwidth and transmission power) using a non-orthogonal multiple access (NOMA) …

Non-orthogonal multiple access (NOMA) has been recognized as a promising multi-user
access technique for the next generation cellular communication networks. In this chapter …

In sixth generation (6 G) networks, a massive number of users and devices must be
connected, necessitating flexible resource allocation. In this context, non-orthogonal multiple …
