Extended space-time multilevel coded spatial modulation

A new space-time coding scheme is drawn based upon the concepts of multilevel coding, space-time block coding (STBC), and spatial modulation (SM). In light of a STBC-SM scheme, an interblock-correlated multilevel code is combined in conjunction with set partitioning of the expanded transmission matrix set according to the coding gain distance criterion. The error performance of an example code is compared with the traditional STBC-SM scheme in computer simulation. Under the situation of the same spectral efficiency and space diversity order, the proposed scheme is superior as regards its bit error performance.
