Design of Spatial Constellation for Spatial Modulation

In order to achieve the transmission of more extra information bits, a new design, called spatial modulation with spatial constellation design (SM-SC), is proposed to extend the size of a spatial constellation diagram in spatial modulation (SM) system by designing the component formation of the transmitted spatial constellation vector (TSV). In our SM-SC, the spatial index bits are made up of two parts: the symbol group index (GI) and antenna...
