Abstract

Non-orthogonal multiple access (NOMA) is a great option for an upcoming radio access network due to its ability to provide enormous connections and high spectral efficiency. However, NOMA's primary issue is the error with successive interference cancellation (SIC). This paper aims to examine bit error rate (BER) downlink (DL) NOMA power domain (PD) for various SNR levels in additive white Gaussian noise (AWGN) as well as in Rayleigh fading channels utilizing Quadrature Phase Shift Keying (QPSK) for three different scenarios, to clearly differentiate the more effect of distance, bandwidth (BW), and power location coefficients factors using the MATLAB simulation software program. The BER versus SNR results were obtained in terms of charts for different BWs, distances, and power location coefficients. According to the findings, the BW parameter has the strongest effect on BER DL NOMA PD when compared to the distance, and power location coefficient parameters.
