Capacity Improvement of Space Time Block Code Spatial Modulation for Three Transmit Antennas

Abstract A new technique is proposed in this paper to increase the capacity of space time block code-spatial modulation (STBC-SM) by 0.5 bit/s/Hz. This technique is achieved by doing a switching between STBCSM and SM in order to increase the capacity. The Bit Error Rate (BER) of this scheme is evaluated by MATLAB simulation, and it is found that it has a better performance compared with that of the hybrid STBC (for the same capacity) by about 6-4 dB at BER of 10.
