| Abstract(in English) | Recently, non-orthogonal multiple access (NOMA) scheme has been proposed to increase the spectral efficiency of wireless communications. As ones of them, low-density signature (LDS) and sparse code multiple access (SCMA) have been proposed. We also have proposed a sparse chaos code multiple access (SCCMA) that has physical layer security ability. Meanwhile, the usage scenario of massive machine type communications (mMTC) in which massive internet of things (IoT) devices transmit short packets in a grant-free manner is considered in the fifth generation mobile communications system (5G). Therefore, we propose a grant-free SCCMA that realizes secure NOMA for mMTC by exploiting a random signal spreading feature in codebook design. |
