| Abstract(in English) | To realize higher-capacity wireless access systems, a non-orthogonal multiple access (NOMA) scheme, in which a superimposed radio resource allocation is allowed and dense multiple access is enabled, has been studied recently. As one of NOMA technologies, low-density signature (LDS) and sparse code multiple access (SCMA) have been proposed. In these schemes, mapping signals are superimposed in a round robin scheduling manner, and an overloaded transmission up to about 150 % is conducted. In particular, SCMA utilizes near-random signatures as mapping signal, and a shaping gain is obtained over LDS that has almost a constant signal envelope. Here, we have proposed a chaos multiple-input multiple-output (C-MIMO) transmission scheme that has both physical layer security ability and channel coding gain, and the transmit waveform of C-MIMO is Gaussian. Thus, the principle of C-MIMO can be applied into SCMA. Therefore, in this paper, we propose a sparse chaos code multiple access (SCCMA) scheme that has overloaded transmission function and physical layer security. The performances of bit error rate and security are shown through computer simulations. |
