Many known second-order statistics (SOS)-based blind algorithms for MIMO channel estimation, including the subspace (SS) and linear prediction (LP) method, are sensitive to channel-order overestimations. To overcome this problem, an algorithm is proposed in [IEEE Trans. Signal processing 50(6) (2002) 1449–1458] for the SIMO system only, and then its simple generalization to the MIMO system is presented...
A new second-order statistics (SOS)-based blind algorithm for MIMO channel estimation 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 in Gazzah et al. (IEEE Trans. Signal Process. 50(6)(2002)1449), this method is truly...
