This structure has an estimation error that is a linear function of the coefficients. This property greatly simplifies the derivation of gradient-based algorithms. Computer simulations show that the proposed structure improves convergence speed.987-989engAdaptive filteringComputer simulationConvergence of numerical methodsDigital filtersError analysisErrorsEstimationIdentification (control systems)Estimation errorMean square errorPrefiltering algorithmAlgorithmsTrabalho apresentado em evento10.1109/MWSCAS.1995.510257WOS:A1996BF75Z00245Acesso aberto2-s2.0-0029461772
