In this paper, we evaluate the performance of NOMA system in downlink scenario over a well-known generalized fading channel called α-η-μ in terms of the Average Bit Error Rate (ABER). The exact closed-forms of Average Bit Error Rate (ABER) for two NOMA users case are obtained in this work in order to study the significant of different fading parameters such as the non-linearity ($\alpha$), the different power between the in-phase and quadrature components of the signal $(\eta)$, and the amount of multipath clusters $(\mu)$. Therefore, the Bit Error Rate (BER) of BPSK modulation technique is averaged by the probability of density function (PDF) of frequency flat fading channel modelled by α-η-μ fading distribution. This work is being validated via a Monte Carlo Simulation to show the correction of the analytical derivations. However, this particular generalized fading channel can introduce other non-homogeneous attributes of the transmission medium such as Rayleigh, Weibull, Nakagami-m, $\alpha-\eta, \alpha-\mu$ fading channel models as special cases, which makes it more essential and worthy to be investigated.
