Abstract- Due to massive connectivity and increasing demands of various services and data applications, fifth generation (5G) wireless systems requires more effective radio access techniques. Non-orthogonal multiple access (NOMA) has recently gained ever-growing attention from both academia and industry. Compared to orthogonal multiple access (OMA) techniques, NOMA is superior in terms of spectral efficiency and is thus appropriate for 5G and beyond. We provide an overview of NOMA principles and applications. NOMA uses superposition coding at the transmitter such that the successive interference cancellation (SIC) receiver can separate the users both in the uplink
and in the downlink channels.
Keywords- NOMA, 5G, OFDMA, SIC
