Two antenna selection algorithms, namely the Euclidean Distance optimized Antenna Selection (EDAS) and Capacity Optimized Antenna Selection (COAS) are studied in the context of Spatial Modulation (SM) systems operating with the aid of imperfect Channel State Information at the Receiver (CSIR). The Symbol Error Rate (SER) performance of these schemes is compared to that of the conventional MIMO (CMIMO) system employing transmit antenna selection. It was observed that the SM system employing antenna selection attains significant Signal-to-Noise Ratio (SNR) gains compared to the C-MIMO system employing antenna selection, especially in the low to moderate SNR regime. Furthermore, we propose a lowcomplexity iterative data-detection/channel-estimation algorithm for the SM system operating with imperfect CSIR that offers an almost identical SER performance as that of the SM system operating with perfect CSIR. Index Terms ?? Spatial modulation, antenna selection, limited feedback, diversity, and capacity.
