Abstract
A generic representation of fast least squares algorithms based on the QR decomposition technique is given, pointing out the equivalence with the normalized lattice. The numerical stability observed in simulations is justified, and the implementation in adaptive filters is discussed, with emphasis on the computational complexity issue
