In this study, a new correntropy Independent Component Analysis (ICA) based blind channel estimator for Multiple-input Multiple-output Orthogonal Frequency-Division Multiplexing (MIMO-OFDM) is proposed. Simulation results show that performance of the proposed method is better than that of Second-Order Blind Identification (SOBI) based method for temporally correlated sources.
