| Abstract(in English) | As one of the main scenarios in the fifth generation mobile communications system (5G), a massive machine type communications (mMTC), that accommodates Internet of things (IoT) device connections, is considered, and a non-orthogonal multiple access (NOMA) scheme is recognized as a realizing technology for mMTC. In the NOMA schemes, we have proposed a grant-free sparse chaos code multiple access (GF-SCCMA), which applies chaos secure communication scheme into NOMA to achieve a large-capacity transmission and the physical layer security. Furthermore, we have proposed an application of Gaussian belief propagation (GaBP) into GF-SCCMA decoding for realizing large-scale connections, and have showed its superior performances. However, the theoretical analysis of GaBP-based GF-SCCMA was not considered. Therefore, in this paper, we analyze the performance of the proposed scheme by the EXIT charts and show the performance advantage for the conventional GaBP-based GF transmission scheme. |
