In this study, we propose a transmission scheme Space time block coding which is integrated with spatial modulation to improve the diversity of the system and also to reduce the inter-channel interference. At the transmitter end, for the given number of antennas the data is modulated and antenna indices and combinations are considered for their transmission. At the receiver end a maximum likelihood(ML) decoder, which is a low complexity decoder is considered to recover the original information bits. The simulation results shows the bit error rate performance of the system for various modulation techniques.
