abstract = "Orthogonal Multiple Access (OMA) schemes provide limit on the number of users and do not meet 5th generation requirements. Non-Orthogonal Multiple Access (NOMA) improves spectral efficiency and user capacity without sacrificing system performance. In order to develop link adaptation mechanism for 5G communication technology based on NOMA, detailed parametric analysis and computation of bit error rate (BER) bounds is an essential requirement. Major focus of this paper to evaluate performance analysis, based on the BER curve of CD-NOMA and PD NOMA using different parameters. The chosen schemes for Code Domain NOMA are LDS-CDMA, LDS-OFDM and SCMA. Power Domain NOMA is implemented for two user model. CD NOMA schemes are compared with PD NOMA and their fair comparison is evaluated. All schemes are run in MATLAB under AWGN Channel. There system model, key performance parameters and achieved results are discussed. From analysis, we obtained better results for LDS-OFDM amongst LDS-CDMA and SCMA for six users. LDS-OFDM model results, which is run for six users is closed to Power Domain NOMA run for two users.",
