Exploitting Performance Of Miso Based Non-Orthogonal Multiple Access

This paper examines non-orthogonal multiple
access (NOMA) and explores the effect of multiple antenna
equipped at base station to serve many users who expect to
multiple access to core network. This system model using
multiple input single output (MISO) contributes enhancement on
the outage performance of two NOMA end-users. We first
introduce a simple model of power distribution to NOMA users
who use both direct link and relay link to improve quality of
transmission. Inspired by NOMA strategy, we then identify
signal to noise ratio to discover separated signal for each user,
and exact expressions of outage probability are developed in
assumption that receiver can eliminate the interference
completely with successive interference cancellation. Theoretical
and simulation results show that the both suggested models can
achieve the remarkable performance improvement of two
NOMA users
