Non-Orthogonal Multiple Access (NOMA) Dynamic Power Allocation in 5G Networks

open access: yesWasit Journal of Engineering Sciences, 2022
Abstract The thought of non-orthogonal multiple access (NOMA) are given as a potential radio access method for versatile correspondence networks past the fourth era (4G). As opposed to current long haul development radio access procedures, non-symmetrical different access involves the power space for client multiplexing at the transmitter and ...

Coordinated Beamforming for Multi-Cell Non-Orthogonal Multiple Access-Based Spatial Modulation

open access: yesIEEE Access, 2020
This paper proposes coordinated beamforming (CB) that works over non-orthogonal multiple access (NOMA) scheme integrated with spatial modulation (SM), termed as CB NOMA-SM, to improve capacity and user fairness. User capacity, ergodic sum capacity (ESC),

Resource Allocation for Non-Orthogonal Multiple Access (NOMA) Enabled LPWA Networks [PDF]

open access: yes2019 IEEE Global Communications Conference (GLOBECOM), 2019
In this paper, we investigate the resource allocation for uplink non-orthogonal multiple access (NOMA) enabled low-power wide-area (LPWA) networks to support the massive connectivity of users/nodes. Here, LPWA nodes communicate with a central gateway through resource blocks like channels, transmission times, bandwidths, etc.

A Novel Downlink IM-NOMA Scheme

open access: yesIEEE Open Journal of the Communications Society, 2021
In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements on quality of service forces

A Novel Opportunistic NOMA in Downlink Coordinated Multi-Point Networks [PDF]

open access: yes, 2016
The non-orthogonal multiple access (NOMA) is regarded as a promising multiple access technique for 5G networks. In this research, we consider the joint transmission (JT) NOMA for a Coordinated Multi-Point (CoMP) system, and propose anovel opportunistic ...

Outage Probability analysis of Power Domain MISO-NOMA in Rayleigh Fading Channel

open access: yesSir Syed University Research Journal of Engineering and Technology, 2022
The multiple access technique of the current wireless communication system depends on the orthogonal multiple access (OMA) technique. The availability of orthogonal resources is limited in OMA and cannot support the increasing demand for a large number ...

Power Allocation Evaluation for Downlink Non-Orthogonal Multiple Access (NOMA) [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2020
Fifth-generation of wireless cellular systems has the potential to increase capacity, spectral efficiency, and fairness among users. The Non-Orthogonal Multiple Access based wireless networks (NOMA) is the next generation multiplexing technique. NOMA breaks the orthogonality of traditional multiple access to allow multiple users to share the same radio
