Non-Orthogonal Multiple Access (NOMA) Dynamic Power Allocation in 5G Networks
Wasit 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
IEEE 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]
2019 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
IEEE 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

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