| Abstract(in English) | To realize massive machine type communications (mMTC) scenario which accommodates Internet of things (IoT) device connections in the fifth generation mobile communications system (5G), non-orthogonal multiple access (NOMA) schemes have been considered. As one of NOMA schemes, we have proposed a grant-free sparse chaos code multiple access (GF-SCCMA), which applies a chaos secure communication into NOMA. It was shown that a large-capacity mMTC with physical layer security was realized by GF-SCCMA when overloaded transmission was composed with using message passing algorithm at the receiver. However, these performances were analyzed by numerical simulations and theoretical analysis was not considered. Then, in this paper, we calculate the constellation constraint sum capacity of GF-SCCMA and compare it to other NOMA schemes. In addition, the EXIT charts when low-density parity check code is concatenated are drawn, and the good performance of GF-SCCMA is theoretically analyzed. |
