Abstract

In this paper a brief survey is carried out on NOMA for wireless schemes, where in Buffer aided Non-orthogonal multiple access relaying system in Rayleigh fading channel is discussed on context of outage probability reduction and increasing transmission rate. NOMA for multiple antenna relaying networks briefs about usage in cellular communication adopting transmit antenna selection at base station and maximal ratio combining (MRC) a mobile users. NOMA in coordinated Direct and relay transmission focuses on performance gain.
