Abstract

In this work, an advanced novel small-scale non-orthogonal multiple access (NOMA) utilizing physical layer security (PLS) techniques used for enhancing communication security and reliability for two users is proposed. This work is motivated by current challenges faced by the conventional NOMA techniques. For instance, the recent exclusion of power-domain NOMA (PD-NOMA) from 3GPP release 17 due to its performance degradation. The efficiency and novelty of the proposed system are presented via mathematical analysis and validated by Monte Carlo simulations. Results indicate that the proposed model achieves secure and efficient communication, suitable for low power consumption and limited processing applications.
