Non-orthogonal multiple access (NOMA) has been envisaged as a key driving scheme for
future wireless communication systems because of its huge connecting ability and superior …

This paper investigates applications of multiple-input multiple-output (MIMO) in non-
orthogonal multiple access (NOMA) for downlink multiuser systems, where the total number …

Although the theory of nonorthogonal multiple access (NOMA) has been widely investigated,
so far, there is a lack of applying beamforming into NOMA systems. In this article, we …

This article investigates several critical issues on the ergodic sum capacity and system
outage performance of downlink non-orthogonal multiple access (NOMA) systems with …

Non-orthogonal multiple access (NOMA) is currently considered as a promising technology
for the next-generation wireless networks. In this paper, the error rate performance of NOMA …

Non-orthogonal multiple access (NOMA) is a promising technology to increase system
throughput and accommodate massive connectivity via non-orthogonal resource allocation …

Abstract Non-Orthogonal Multiple Access (NOMA) is a technique to support a massive
number of users to access the radio resources simultaneously and frequently. Existing …

Non‐orthogonal multiple access (NOMA) is a potential technology for the fifth‐generation
(5G) cellular systems. The main task of the user pairing (UP) in NOMA is the selection of the …

In this paper, we tackle the problem of optimizing user clustering, power, and resource (time
slot or bandwidth) allocation in the downlink of a hybrid non-orthogonal multiple access …

In this paper, antenna diversity is used to improve the outage performance of downlink non-
orthogonal multiple access (NOMA) systems combined with single-user multiple-input …
