|摘要:||Most of the studies on spatial modulation (SM) signal detection assume perfect channel state information (CSI) and ignore the channel\'s time-spatial correlation. Performance degradation incurs in the presence of imperfect CSI and channel correlations when estimating or predicting channel state based on periodic pilots. Detector structures that take into account both the channel estimation error and time-spatial correlation are investigated in this paper. We propose the CSI error and channel correlation aware ML detectors in conjunction with two channel estimation methods and present numerical results to quantify the associated performance improvements.|
