Performance Analysis of Downlink NOMA System over α−η−μ Generalized Fading Channel

Research output: Contribution to conferencePaperpeer-review


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 (α), the different power
between the in-phase and quadrature components of the signal
(η), and the amount of multipath clusters (μ). 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, α−η, α−μ fading channel models as special cases,
which makes it more essential and worthy to be investigated.
