ShanDong labor vocational and technical college Jinan, China Abstract-Spatial Modulation (SM) is a recently emerged Multiple-Input Multiple-Output (MIMO) technique, which has been proved to be low-complexity and more energy-efficient compared with classical MIMO techniques. As an entirely novel hybrid modulation scheme, the performance of SM is highly dependent on the specific type of digital modulation schemes, and the digital modulation constellation optimizing is still a problem. In this paper, a novel digital modulation constellation design method suitable for SM transmission is proposed, which has multi-ring structure with each ring's constellation similar with PSK constellation. Both analysis and simulation results show that the novel designed multi-ring constellation could provide superior performance compared with traditional PSK and QAM over independent Rayleigh fading channels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
