Abstract
A generalized spatial modulation (SM) scheme with multiple active transmit antennas, named as multiple active spatial modulation (MA-SM) and multiple-input multiple-output (MIMO) transmission scheme, called space-time block coded spatial modulation (STBC-SM) are proposed in this paper. Also different modulating techniques are implemented. The combination of spatial modulation (SM) and space-time block coding (STBC) to take advantage of the benefits of both while avoiding their drawbacks. In the MA-SM system, the transmitted symbols are mapped into a high dimensional constellation space including the spatial dimension. The general principle for designing the efficient MA-SM for arbitrary number of transmits antennas and modulation scheme is presented. Moreover, a near-optimal detection scheme with low complexity for MA-SM is also proposed and analysed. A general technique is presented for the design of the STBC-SM scheme for any number of transmits antennas. The performance advantages of the STBC-SM over simple SM and over V-BLAST are shown by simulation results for various spectral efficiencies and are supported by the derivation of a closed form expression for the union bound on the bit error probability.
