Twofold concatenation of space-time coded spatial modulation

A new space-time coding scheme is drawn upon the concepts of concatenation, multilevel coding, and spatial modulation. In light of a space-time block coded spatial modulation scheme, several component codes are combined in conjunction with set partitioning of the transmission matrix set according to the coding gain distance criterion. Then, the associated scheme is further concatenated with an outer Reed-Solomon code. Simulation results show that the proposed scheme is superior as regards its bit error performance.
