Abstract
In this paper, a novel transmission scheme is proposed to improve the data rates of spatial modulation (SM) which has low complexity and improves the spectral efficiency in correlated channel environments. The conventional SM scheme utilizes partial multiple antennas to transmit signal constellations and additional bits using antenna combinations. Therefore the channel capacity of SM is less than that of the conventional multiple input-multiple output (MIMO) scheme which uses all the available antennas. In this paper, an SM transmission scheme is proposed to improve the channel capacity using a tight frame pre-coder. The improvement in channel capacity of the SM scheme will be shown using computer simulations.
