Survey of Capacity Calculation for Non Orthogonal Multiple Access (NOMA) transmission scheme over DF and AF relaying

Abstract

The objective of the paper is to improve the capacity of the communication channel and to reduce the bit error rate for the transmission. From the various literatures, it clearly defines that the capacity can be improved by means of Non Orthogonal Multiple Access (NOMA) transmission scheme compared to Orthogonal Multiple Access (OMA) transmission scheme. This paper mainly deals with the analysis of capacity for NOMA transmission scheme with Decode and Forward relaying and Amplify and Forward relaying and compared with OMA transmission scheme.
