Abstract: NOMA (Non-Orthogonal Multiple Access) is a unique method for enhancing the spectral efficiency and resource usage of wireless networks. Here everyone transmits the data on same frequency and time resource in parallel according to the different power level or modulation scheme assigned to each user. This gives the system the ability to scale their network and support more users efficiently. NOMA further boosts the performance in large HetNets for 5G and beyond by employing various schemes such as interference cancelation by Successive Interference Cancellation (SIC) at power domain at receiver and superposition coding. this paper presented a comprehensive study for NOMA (SPC) at technology and presented various way to transmitter improve the NOMA per for mance from pervious study.
