To address this concern, an optimal maximum likelihood detector is proposed for SM-based transmission and the system performance is analyzed by computer simulations and analytical derivations. In addition, this optimal receiver is compared with a nonoptimal receiver. Specifically, pairwise and average bit error probabilities are derived for the optimal detector. The results prove that IQI is a critical issue for SM-based transmission and the proposed optimal receiver significantly enhances the SM system performance in the presence of IQI.Elektronikeninfo:eu-repo/semantics/closedAccessError Performance AnalysisMühendislik Temel Alanı->Elektrik-Elektronik MühendisliğiI/Q İmbalanceMaximum Likelihood DetectionSpatial ModulationArticle10.1109/LCOMM.2018.2836448
