UNEQUAL-LENGTH MULTICHANNEL DELTA(B)-LEVINSON AND SCHUR TYPE RLS ALGORITHMS

In this correspondence, delta(b)-operator-based unequal-length multich annel Levinson and Schur-type RLS algorithms are developed which have the potential of improved numerical behavior for fast-sampled or ill-c onditioned input data. They provide computational improvement over the overparameterization, or the zero padding approach using the existing equal-length multichannel delta(b) algorithms when an unequal length multichannel case is considered.
