Performance of downlink NOMA with multiple antenna base station, full-duplex and D2D transmission

Abstract

The implementation of non-orthogonal multiple access (NOMA) and transmit antenna selection (TAS) technique has considered in this paper since TASaware base station (BS) provides the low cost, low complexity, and high diversity gains. In this paper, we investigate performance of two users by deriving outage probability. The system performance benefits from design of TAS and full-duplex (FD) scheme applied at NOMA users, and bandwidth efficiency will be enhanced although self-interference exists due to FD. The main contribution lies in the exact expressions of outage probability which are derived to exhibit system performance. Different from the simulated parameters, the analytical results show that increasing number of transmit antennas at the BS is way to improve system performance.

BER-performance evaluation for 5G-PD-NOMA system in multipath communication channels

“…In NOMA communication system, high computation power is needed in order to implement power allocation and successive-interference-cancelation (SIC) at both transmitter/receiver sides respectively [6]- [14]. There are many benefits were introduced as a result of implementing NOMA technology in 5G networks such as; minimum latency communication with throughput improvement, good reliability with extremely massive connectivity [15]- [18]. NOMA technology was introduced with to approaches; power domain (PD) and coding domain (CD) [19].…”
