In this contribution, the system of quasi-orthogonal space-time block coded spatial modulation (QOSTBC-SM) with minimum decoding complexity (MDC) is proposed toward linear detection complexity by utilizing the corresponding single-symbol decoding algorithm at the receiver. In addition, we compare the performance of the MDC-QOSTBC-SM system with different decoding algorithms in conjunction with comparing this scheme with space-time block coded spatial modulation (STBCSM). Furthermore, we extend it to uplink multi-user multiple-input multiple-output (MIMO) communications and compare the performance with STBC-SM in the context of quasi-static flat Rayleigh fading channels. The simulation results indicate that the proposed scheme achieves a significant reduction in decoding complexity at the cost of a slight performance loss when employing the single-symbol decoding algorithm.
