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 …

To improve the throughput per channel in multichannel nonorthogonal multiple access
(NOMA) random access (RA) system, users (re) transmit their packet to one of the channels …

Using wireless uplink non-orthogonal multiple access (NOMA), the throughput of an uplink
random access system can be significantly improved. In this letter, assuming that each user …

In this paper, we study the joint resource allocation and the corresponding performance of
non-orthogonal multiple access (NOMA) systems with imperfect successive interference …

In this paper, resource allocation for a multi-carrier uplink non-orthogonal multiple access
(NOMA) system is studied. Unlike the existing works on multi-carrier uplink NOMA, in which …

We investigate joint power allocation and decoding order selection (PA-DOS) aimed at
enhancing the outage performance of non-orthogonal multiple access (NOMA) systems. By …

In the fifth generation (5G) wireless communication system, the non‐orthogonal multiple
access (NOMA) scheme has recently been proposed as a possible candidate for improving …

Non-orthogonal multiple access (NOMA) has been investigated as a candidate radio access
technology for the fifth generation mobile networks. In this paper, we focus on the dynamic …

Power allocation plays an important role in cooperative non-orthogonal multiple access
(NOMA) systems. To guarantee the quality of service (QoS) requirements of users, we …

In order to exploit the multiuser diversity in uplink non-orthogonal multiple access (NOMA)
systems, we adopt the concept of the cumulative distribution function (CDF)-based …
