Performance Evaluation of Non Orthogonal Multiple Access (NOMA) with digital modulation schemes

Non Orthogonal Multiple Access (NOMA) isnew significant research area, as it gives novel idea ofmultiplexing the communication channels on the samefrequency and time slot , which can present revolutionaryoutcomes.The general idea of (NOMA) is based on usingSuccessive Interface Cancelling (SIC) , where each user ofthe channel is distinguished by its unique power level, andthen all the users are modulated/demodulated in certainorder.In this study, many experiments are run to examineNOMA with digital modulation schemes, such as ASK, PSK,FSK, QPSK, and 8 QAM. MATLAB codes are built toperform each experiment.According to the performed simulation, 8-QAM has thelowest Bit Error Rate (BER).
