| Abstract | With ever increasing demand and progress of telecommunication networks (4G, 5G and beyond) in industrial automation, smart cities, internet of things and vehicular communication, some of the key goals or challenges that need to be talked are capacity enhancement, better data rate, increased spectral efficiency, reduced latency and better Quality of Service (QoS) and Quality of Experience (QoE) to mobile users. The limitations of the 3G and 4G networks lies in the capacity because of the Orthogonal Multiple Access (OMA) they use in time, frequency, and code domain. To overcome this limitation 5G NR (New Radio) is developed by 3GPP. The multiple access technique used in 5G network is Non-Orthogonal Multiple Access (NOMA). This paper presents results of review and basic implementation of NOMA operations like superposition coding, Successive Interference Cancellation (SIC) and effect of it on bit error rate (BER) curve for two users and three users with different power weights. Authors have found that with large difference in the power weights assigned to user there is significant difference in the BER of users after decoding, also by changing the power weights assigned to users BER can be reduced at lower values of SNR. © 2023 IEEE. |
