| Abstract(in English) | In mobile uplink channels of advanced driver assistance systems, transmission schemes with low-latency, high-quality, and on-demand scheduling-less are required. As one of its solutions, sparse code multiple access (SCMA) and low-density signature (LDS) have been proposed. These schemes are kinds of non-orthogonal multiple access schemes in which mapping signals are superimposed without scheduling, and an overloaded transmission up to about 150 % is conducted. However, the detailed transmission characteristics of SCMA and LDS were not illustrated. Therefore, in this paper, we numerically analyze the performances of SCMA and LDS in a few configurations and channel environments by simulation, and compare them to orthogonal frequency division multiple access (OFDMA) under the same conditions. |
