Abstract—This paper proposes a low-complexity near-maximum-likelihood (ML) detector for space-time block coded spatial modulation with cyclic structure (STBC-CSM). The proposed detector yields a significant reduction in computational complexity compared to the traditional ML detector, while simulation results demonstrate near-ML error performance. The union bound theoretical framework to quantify the average bit-error probability of -ary quadrature amplitude modulation STBC-CSM over a frequency-flat Rayleigh fading channel is formulated and validates the Monte Carlo simulation results.
