RESUMO

This work is concerned with the adaptive parameter estimation via linear least-squares subject to linear equality constraints. Recursive algorithms are proposed for solution of least-squares problems with exponential data weighting and sliding data window, by combining normal equations and orthogonal factorization with the null space of the constraint matrix and Lagrange multipliers. A numerical example ilustrates the proposed algorithm performance in the design of a finite impulsive response filter (FIR) for frequence detection in a signal with noise
