This paper proposes a clustering-based blind detector for Multiple-Input Multiple-Output (MIMO) system using Space Shift Keying (SSK) modulation. First, we map the considered detection problem to a clustering problem. Second, we use the well-known k-means clustering algorithm to design the detector for the considered MIMO system. Third, the proposed k-means clustering detector (KMC detector) for a blind receiver can provide comparable performance to that of the optimal receiver with perfect
