Abstract(in English) In the fifth generation mobile communications system (5G), as a realizing technology for accommodating the wireless connection of massive Internet of things (IoT) devices, grant-free non-orthogonal multiple access (NOMA) schemes have been considered. In NOMA schemes, both system capacity enhancement and transmit protocol simplification are achieved, and an overloaded transmission of more than one hundred percent of the capacity for the number of transmission samples is conducted. As one of the representative schemes of NOMA, multi-user shared multiple access (MUSA) has been proposed. However, the performance of MUSA is not fully analyzed nor compared to other NOMA or orthogonal multiple access schemes. Therefore, in this study, we numerically analyze the performances of MUSA in uplink fading environments and compare them with orthogonal frequency division multiple access (OFDMA), space division multiple access (SDMA)-based OFDMA, low-density signature (LDS), and sparse code multiple access (SCMA). Then, the characteristics and superiority of MUSA are clarified.
