摘要：
In order to meet the 5G requirements on spectral efficiency and the number of connections, new multiple access (NMA) is becoming an important technology in 5G. Different from orthogonal multiple access (OMA), NMA technology is tolerant of symbol collisions in orthogonal channels, thereby significantly increasing the number of served users. In this paper, a unified framework of NMA is proposed for the next generation radio access networks. The evaluation results of several NMA schemes, such as sparse code multiple access (SCMA), pattern division multiple access (PDMA) and interleaver-grid multiple access (IGMA), are given. And the results show that NMA can obtain significant block error rate (BLER) performance gain, compared with orthogonal frequency division multiple access (OFDMA).
