Abstract
In this paper, we propose a semi-blind super-vised learning(SL)-based detector for spatial modulation (SM) multiple-input multiple-output (MIMO) systems, which has low cost and low complexity. Specifically, the proposed scheme exploits the the rotation characteristic of constellation symbols for reducing the the length of the training sequence required for accurate signal classification. We proved that this reduction causes no performance loss compared with the conventional SL detector that uses the full length of training sequence. Moreover, we found that the ratio of the reduction depends on the specific constellation type. Our simulation results show that the proposed SL detector is capable of reducing up to 81% training load and complexity compared to the conventional SL detector.
