A new second-order statistics (SOS) based blind algorithm for MIMO channel identification is proposed. It can give estimations of all channel impulse responses subject to a scalar matrix ambiguity which is intrinsic to all SOS based blind methods. As a generalization of the blind identification algorithm for SIMO system, this method is truly robust to channel order overestimation, i.e., it can accurately estimate the channels when only upper bounds for all MIMO channel orders are known.
