This paper introduces a new spatial modulation scheme which subsumes both the previously introduced spatial modulation (SM) and generalized SM for wireless multiple input multiple output transmission. We apply the concept of spatial constellation (SC) codeword for the so-called spatially modulated space-time block code (SM-STBC) to the case of SM and introduce a new method to design the spatial codewords. Compared to other SM schemes the proposed high-rate SM (HR-SM) achieves significant increase in spectral efficiency for only small additional number of antennas. For the same spectral efficiency, the proposed HR-SM also outperforms the popular Alamouti space-time block code (STBC) and V-BLAST scheme in terms of BER performance.
