Now a days, the non-orthogonal multiple access is one of proposed scheme for fifth generation (5G), it is called sparse code modulation (SCMA) with low complexity massage passing algorithm (MPA). To show how the performance of SCMA, the MPA system could be adopted to get near with maximum likelihood (ML) detection performance under less-complexity. The MPA algorithm is performed by the specific codebook in SCMA transceiver scheme with many types of MPA, such as SD-MPA, DS-MPA, and PM-MPA. From the three specific model DS-MPA shows better performance in low SNR, while the SD-MPA should get near result with DS-MPA in different condition. As known that the typical 5G use cases identified by ITU-T and adopted by 3GPP allowed SCMA for massive machine type communication (mMTC), SCMA can be one of this solution with low complexity scheme. It has some promising function, such as relaxes orthogonality, resistance to multi-user interference, enabler of simplified scheduling, and enabler of grants-free transmission.
