Abstract :
Multiple regularization parameters to modify the Moore-Penrose type of pseudo-inverse matrix are introduced. Two methods for determining these optimal parameters are shown: the first is based on minimization of an estimated mean squares error (EMSE) criterion calculated by using only accessible signal data, and the second is based on minimization of the Akaike Bayesian information criterion (ABIC). The proposed schemes can be extensively applied to separation of the signal subspace and noise subspace
