Spatial modulation (SM) is a low complexity modulation scheme which is recently proposed for multiple antenna wireless systems. SM is unable to achieve transmit diversity but it provides multiplexing gain by averting inter channel interference with respect to single antenna system. A new modulation concept which combine high multiplexing gain of SM and transmit diversity gain provided by Space Time Block Codes (STBCs) to take advantages of merits of both while avoiding their demerits is referred to as " Spatially–Modulated STBCs " (SM–STBCs). In this scheme the transmitted information symbol are expanded not only to space and time domain but also to spatial (antenna) domain and therefore both core STBC and antenna indices carry information. A low-complexity maximum likelihood (ML) decoder is described for the new scheme which profits from the orthogonally of the core STBC.
