Impact of Factor Graph on Average Sum Rate for Uplink Sparse Code Multiple Access Systems
IEEE Access, 2016 In this paper, we first study the average sum rate of sparse code multiple access (SCMA) systems, where a general scenario is considered under the assumption that the distances between the mobile users and the base station are not necessarily identical ...
