Relay Selection for Cooperative NOMA [PDF]

open access: greenIEEE Wireless Communications Letters, 2016
—This letter studies the impact of relay selection (RS) on the performance of cooperative non-orthogonal multiple access (NOMA). In particular, a two-stage RS strategy is proposed, and analytical results are developed to demonstrate that this two-stage strategy can achieve the minimal outage probability among all possible RS schemes, and realize the ...

Performance Analysis of IRS-Aided NOMA Communications in the Presence of Imperfect SIC [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2021
The intelligent reflecting surface (IRS) is expected to be a promising technique to achieve a robust spectrum and energy efficiency. This paper investigates the advantages of IRS in enhancing performance of non-orthogonal multiple access (NOMA ...

The Performance Evaluation of NOMA for 5G Systems Using Automatic Deployment of Multi Users [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
Non-Orthogonal Multiple Access (NOMA) in the fifth generation (5G) system is one of the optimistic technologies for wireless radio access networks. Compared to orthogonal multiple accesses (OMA) reduce the spectral efficiency; NOMA provides the best ...

Faster-Than-Nyquist Asynchronous NOMA Outperforms Synchronous NOMA [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2022
Faster-than-Nyquist (FTN) signaling aided non-orthogonal multiple access (NOMA) is conceived and its achievable rate is quantified in the presence of random link delays of the different users. We reveal that exploiting the link delays may potentially lead to a signal-to-interference-plus-noise ratio (SINR) gain, while transmitting the data symbols at ...

NOMA-2000 Versus PD-NOMA: An Outage Probability Comparison [PDF]

open access: yesIEEE Communications Letters, 2021
Non-orthogonal multiple access (NOMA) is an emerging technique promising to accommodate the increasing data rate requirements of next generation networks. In power-domain (PD) NOMA, this challenge is addressed by allocating two or more users on each orthogonal resource block while assigning significantly different power levels to all users.

Exploiting Full-duplex and Fixed Power Allocation Approaches for Dual-hop Transmission in Downlink NOMA

open access: yesAdvances in Electrical and Electronic Engineering, 2021
In a wireless system, dual-hop transmission requires Full-Duplex (FD) to transmit signals from the base station too far users. It is more beneficial if we deploy non-orthogonal multiple access to serve specific users, i.e.

Outage Performance of Full-Duplex Unmanned Aerial Vehicle-aided Cooperative Non-orthogonal Multiple Access

open access: yesAdvances in Electrical and Electronic Engineering, 2023
Unmanned Aerial Vehicles (UAVs) are envisioned to play a key role in the Sixth-Generation (6G) and Beyond Fifth-Generation (B5G) networks. Resolving spectrum constraints in UAV communications remains a critical issue.

Power allocation‐Assisted secrecy analysis for NOMA enabled cooperative network under multiple eavesdroppers

open access: yesETRI Journal, 2021
In this work, the secrecy of a typical wireless cooperative dual‐hop non‐orthogonal multiple access (NOMA)‐enabled decode‐and‐forward (DF) relay network is investigated with the impact of collaborative and non‐collaborative eavesdropping.
