Abstract :
In this paper, we consider the problem of blind equalization of MIMO systems. In a recent work a blind MMSE equalizer robust to channel order over-estimation errors was proposed for SIMO systems. In this work, we extend this method and propose a new MMSE algorithm that presents better robustness and better tracking performances. Moreover, the proposed MMSE technique has been extended here to the MIMO case. Simulation results are then given to illustrate the effectiveness of our MMSE algorithms
