Abstract

Space-time block coded differential spatial modulation (STBC-DSM) is a recently proposed DSM-based multiple-input-multiple-output (MIMO) transmission technique with high diversity gain. The existing low-complexity detectors for STBC-DSM can be further designed to reduce complexity. In this paper, we propose an ordered antenna index vector detector (OVD) for STBC-DSM, and an OV-low repetition detector (OV-LRD) for further simplification. The OVD detects the symbols in a designed order, and the OV-LRD fully uses the STBC structure to simplify the OVD. Simulation results show that the OVD achieves near-optimal performance, and the OV-LRD significantly reduces complexity with negligible performance loss.
