摘要
OMA (Orthogonal Multiple Access)方案对用户数量有限制，不能满足第五代的要求。非正交多址(NOMA)在不牺牲系统性能的前提下提高了频谱效率和用户容量。为了开发基于NOMA的5G通信技术链路自适应机制，对误码率(BER)边界进行详细的参数分析和计算是必不可少的要求。本文主要重点对CD-NOMA和PD -NOMA在不同参数下的误码率曲线进行了性能评价分析。码域NOMA采用的方案有LDS-CDMA、LDS-OFDM和SCMA。针对两个用户模型实现了功率域NOMA。将CD NOMA方案与PD NOMA方案进行了比较，并对其公平性进行了评价。所有方案都在AWGN通道下的MATLAB中运行。讨论了系统模型、关键性能参数和取得的效果。通过分析，我们在LDS-CDMA和SCMA的6个用户中获得了LDS-OFDM更好的结果。LDS-OFDM模型的6个用户运行结果接近于2个用户的功率域NOMA运行结果。
Comparative Performance Analysis of Code-Domain NOMA and Power-Domain NOMA
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.
