On normalized data-reusing and affine-projections algorithms

This paper addresses the comparison between data-reusing LMS algorithms and the affine-projections algorithm. The normalized new data-reusing LMS (NNDR-LMS) algorithm, the binormalized data-reusing LMS (BNDR-LMS) algorithm, and the affine-projections (AP) algorithm are briefly presented within a common framework and their relationships are clarified. Topics such as equivalence of algorithms, graphical representation, and computational complexity are discussed.
