New adaptive IIR filtering algorithms based on the Steiglitz-McBride method
نویسندگان
چکیده
This correspondence introduces a family of algorithms based on the Steiglitz–McBride (SM) method for adaptive IIR filtering. The main feature of the proposed algorithms is to remove the parameter bias induced by colored measurement noise. The conceptual similarities between the SM method and the equation error (EE) method are explored in order to analyze some properties of the new algorithms. The main analysis results concern the consistency of the parameter estimates and local convergence. A set of simulations in a system identification configuration is included in order to verify the improved performance of the new algorithms based on the SM method.

A consistent Steiglitz-McBride algorithm
An on-line version of the Steiglitz-McBride algorithm that is consistent in the presence of colored noise is proposed. In addition, a proof of local convergence of the new algorithm is provided. Some computer simulations are included showing that the consistent Steiglitz-McBride algorithm is useful for IIR adaptive filtering when the measurement noise is colored.
متن کاملNEW STEIGLITZ-McBRIDE ADAPTIVE LATTICE NOTCH FILTERS
Two novel adaptive notch filters are presented. The updating algorithms are based on the Steiglitz-McBride error criterion minimization and the basic realizations of the notch filters are all-pass based lattice filters. The proposed realizations represent an extension of a previous ad-hoc scheme for adaptive notch filtering and avoid finding the roots of a high order polynomial to obtain the un...
متن کاملAdaptive lattice IIR filtering revisited: convergence issues and new algorithms with improved stability properties
Several algorithms for adaptive IIR filters parameterized in lattice form can be found in the literature. The salient feature of these structures when compared with the direct form is that ensuring stability is extremely easy. On the other hand, while computing the gradient signals that drive the direct form update algorithms is straightforward, it is not so for the lattice algorithms. This has...
متن کاملMisconvergence and stabilization of adaptive IIR lattice filters
We take a new look to adaptive IIR lattice filters in order to devise algorithms that preserve the stability of the corresponding direct form schemes. By analizing the local properties of stationary points, a transformation achieving this goal is suggested, which gives algorithms that can be efficiently implemented. Application to the Steiglitz-McBride and SHARF algorithms is presented. By cont...
متن کاملIIR System Identification Using Improved Harmony Search Algorithm with Chaos
Due to the fact that the error surface of adaptive infinite impulse response (IIR) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. In this case, global optimization techniques are required in order to avoid the local minima. Harmony search (HS), a musical inspired metaheuristic, is a recently ...
