    AbStraCt:   Basic principle of spatial modulation(SM)was introduced.  To deal with  the limitation of the existing detection method, an improved algorithm based on normalized maximum ratio combination(NMRC)  was proposed.  Smulations were performed both in independent and correlated channels.  Results show that the proposed NMRC algorithm can work normally, and for the design of SM system with a certain spectral efficiency,  the configuration of proper transmit antennas and QPSK modulation is preferred.  Compared with V BLAST system, the configuration of SM is more flexible with less complexity for a certain spectral efficiency, while the performance deterioration of SM is more than V BLAST in correlated channels.
