Abstract
In recent days, Non-Orthogonal Multiple Access (NOMA) draws significant attention in 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> generation (5G) mobile communication for its improved spectral efficiency, throughput, user fairness, lower latency, and higher massive connectivity than Orthogonal Multiple Access (OMA). In power domain NOMA (PD-NOMA), Multiuser Superposition Transmission (MUST) method is widely used at the transmitter and Successive Interference Cancelation (SIC) for detection of user data at the receiver. In the present study, we have designed a network with two cells where one cell is operating with OMA and another with NOMA. In NOMA based cell, we increased the no. of users compared to OMA based cell and compare the performance of OMA and NOMA in terms of Bit Error Rate (BER), per-user throughput, and per cell sum throughput in downlink using the Vienna 5G link-level simulator.
