User Clustering and Resource Allocation in Hybrid NOMA-OMA Systems Under Nakagami-m Fading

A Mahmoudi, B Abolhassani, SM Razavizadeh… - IEEE …, 2022 - ieeexplore.ieee.org
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 …

Adaptive clustering of users in power domain NOMA

YP Santos, LFQ Silveira - Sensors, 2023 - mdpi.com
By enabling multiple non-orthogonal transmissions, power domain non-orthogonal multiple
access (PD-NOMA) potentially increases a system's spectral efficiency. This technique can …
