Performance Evaluation of NOMA-assisted Overlay Communication in Energy-Limited Networks

Nonorthogonal multiple access (NOMA) is a promising communication technique that has gained attention in recent years, particularly in the context of energy-limited networks. This approach permits several devices to share the same frequency and time resources, enabling improved spectral efficiency, energy efficiency, and communication reliability. The paper evaluates the performance of NOMA-assisted overlay communication in such networks in terms of innumerable pivotal performance metrics. Numerous results demonstrated the considerable effects of distinct system parameters on the performance of this communication.
