Transmit-Diversity for Spatial-Modulation (SM) & Space-Time Block Codes (STBC)

Abstract: In multiple antenna transmission the multiplexing gain strictly depends on transmit and receive antenna allocation, transmit antenna synchronization and the process used to eliminate the inter channel interference (ICI). Spatial modulation (SM) is a low-complexity scheme for multiple antenna system. The work and research on Spatial Modulation shows that SM is useful to achieve the multi block-code (STBCs) and then splits into n streams which are simultaneously transmitted using n transmitted antenna. Maximum-Likelihood (ML) decoding is achieved by a simple way thro different antenna rather than a joint detection. In other words SM is novel modulation techniques which combines the high multiplexing gain provided by the Spatial Modulation and transmit diversity gain pro (STBCs) technology.
