Non-Orthogonal Multiple Access (NOMA) to Enhance Capacity in 5G

open access: diamondInternational Journal of Contents, 2015
Non-orthogonal multiple access (NOMA) where all users share the entire time and frequency resource has paid attention as one of the key technologies to enhance the spectral efficiency and the total throughput. Nevertheless, as the number of users and SIC error increase, the inter-user interference and the residual interference due to the SIC error also

Interference Regime Enforcing Rate Maximization for Non-Orthogonal Multiple Access (NOMA) [PDF]

open access: green2019 International Conference on Computing, Networking and Communications (ICNC), 2019
An interference regime enforcing rate maximization scheme is proposed to maximize the achievable ergodic sum-rate of the parallel Gaussian interference channels by enforcing very strong interference at receivers through power allocation whenever strong interference is observed.

Reinforcement Learning for Robust Modulation Classification in Non‐Orthogonal Multiple Access (NOMA) Systems

open access: goldIET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a reinforcement learning–based framework for robust modulation classification and resource management in non‐orthogonal multiple access (NOMA) systems. By integrating Q‐learning, deep reinforcement learning, and proximal policy optimisation, the approach enhances spectral efficiency, mitigates interference, and improves ...

Analysis of factors affecting the operation of the communication system with nonorthogonal multiple access [PDF]

open access: yesITM Web of Conferences, 2019
NOMA is a group of non-orthogonal multiple access methods [1]. In this article, we talk about the Power Domain (Division) NOMA method. It is a non-orthogonal multiple access method with channel separation by power [2].

Outage Probability and Ergodic Capacity Analysis of MIMO-NOMA Heterogeneous Network for 5G System

open access: yesJISR on Computing, 2022
Based on the orthogonal multiple access (OMA) paradigm, multiple access techniques are now used in wireless networks. The capacity of OMA for orthogonal resources, which is already constrained, will be exceeded in the coming years by the demand for a ...
