Matlab code for 'NOMA with SiC' and comparison to other OFDMA techniques
The current generation of mobile networks is not designed to meet the future demand for high data rate, low latency communications, support a large number of users. The IMT 2020 has categorized the requirements as enhanced Mobile Broadband (eMBB), Ultra Reliable and Low Latency Communications (URLLC), massive Machine Type Communications (mMTC). The Third Generation Partnership Project (3GPP) has been actively working to define the specifications for next-generation 5G communications to address the requirements. The 3GPP is working across the Core Network (CN) and Radio Access Network (RAN) to meet the requirements. One of the proposed techniques to support a large number of users and high spectral efficiency on the radio multiple access is Non-Orthogonal Multiple Access (NOMA) scheme. This paper provides a study of NOMA, how NOMA addresses the 5G requirements, ongoing standardization efforts for NOMA and a comparative study of NOMA with other OMA schemes like OFDMA. We have also demonstrated improvements in the throughput of the users in NOMA as compared to OFDMA with the help of MATLAB simulations.
