与传统的正交多访问（MA）相比，非正交多访问（NOMA）技术可以实现更高的容量增益和更高的频谱效率，并支持更大的大规模连通性。在本文中，根据信号传输特征，NOMA方案分为四类：基于NOMA，基于NOMA的NOMA，基于NOMA的交织，基于NOMA和基于编码的NOMA。此外，总结了不同方案的过程和特征。评估了NOMA方案的性能。根据评估结果，给出了具有出色性能的方案。通过分析和比较这些技术的功能，可以为将来的5G多次访问提供研究指导。
Compared to the traditional orthogonal multiple access (MA), non-orthogonal multiple access (NOMA) technology can achieve higher capacity gain and higher spectrum efficiency, support larger massive connectivity. In this article, according to signal transmission characteristic, the NOMA schemes are classified into four categories: scrambling based NOMA, interleaving based NOMA, spreading based NOMA and coding based NOMA. Furthermore, the process and characteristics of different schemes are summarized. The performance of the NOMA schemes is evaluated. According to the evaluation results, the scheme with superior performance is given. By analyzing and comparing features of these technologies, a research guiding is given for future 5G multiple access.
