摘要:

In this paper, a block mapping spatial modulation (BMSM) scheme is proposed to increase the transmit rate of multiple-input multiple-output (MIMO) wireless communication systems. In the BMSM scheme, the information to be transmitted is mapped into different combinations of transmit antenna indices and distinct constellation symbols at each time instant. Multiple transmit antennas are activated, which is different from spatial modulation (SM) and generalised spatial modulation (GSM) techniques, and also the information bits to be mapped to the digital constellation diagram exploits block mapping in the BMSM scheme. The multiplexing gain is obtained and the transmit rate is increased. The simulation results for some cases of channel states are presented which verifies the efficiency of the proposed BMSM scheme.
