Abstract :
In this paper, we propose an adaptive receive antenna selection technique for Spatial Modulation (SM) MIMO systems. The proposed method is simple and uses channel state information (CSI) available at the receiver to choose the best subset of active receive antennas among the available Nr receive antennas. Simulation results show that SM MIMO system with the proposed receive antenna selection scheme provides a performance gain of approximately 5 dB over conventional SM system (SM MIMO system without antenna selection). The proposed scheme does not increase the RF chain requirement at the receiver and retains all the benefits of SM MIMO.
