To enable secure and effective downlink multiple-input multiple-output (MIMO) transmission, it has recently been proposed to integrate space-time block code (STBC) with spatial modulation (SM) and artificial noise (AN). However, this technique suffers from high detection complexity at the receiver side. In this contribution, therefore, we present an AN-assisted transmission scheme for the quasi-orthogonal space–time block coded receive spatial modulation (QOSTBC-RSM) system while developing two low-complexity detection algorithms. Our simulation results demonstrate that the proposed scheme and the corresponding detection methods are capable of guaranteeing safe transmission and achieving near-optimal bit error rate (BER) performance while significantly reducing computational overhead.
