| Abstract(in English) | In the standardization of the fifth generation mobile communications system (5G), non-orthogonal multiple access (NOMA) scheme has been proposed to accommodate the communication with a large numbers of Internet of things (IoT) devices. As one of the secure and high-capacity NOMA schemes, we have proposed a grant-free sparse chaos code multiple access (GF-SCCMA) exploiting the principle of chaos communications. It realizes both physical layer security and large-capacity transmission. However, because the decoding is based on a message passing algorithm which needs relatively large complexity, the number of accommodating users in GF-SCCMA is limited. Here, in large-scale multiple-input multiple-output systems, Gaussian belief propagation (GaBP) has been proposed as a low-complexity and high-quality decoding scheme, and the application of GaBP for NOMA has been proposed. Therefore, in this study, we propose an application of GaBP into GF-SCCMA and realize a large-scale GF-SCCMA. The performance of GaBP-based GF-SCCMA is evaluated through numerical simulations. |
