Multichannel fast QRD-LS adaptive filtering: new technique and algorithms
In this paper, a direct, unified approach for deriving fast multichannel QR decompostion (QRD) least squares (LS) adaptive algorithms is introduced. The starting point of the new methodology is the efficient update of the Cholesky factor of the input data correlation matrix. Using the new technique, two novel fast multichannel algorithms are developed. Both algorithms comprise scalar operations...
متن کاملFast QR based IIR adaptive filtering algorithm
In this paper, we present a new QR based algorithm for IIR adaptive filtering. This algorithm achieves a reduction of complexity with regard to the IIR-QR algorithm by using a block reduction transformation. Moreover, this new approach make it possible to directly transform fast FIR algorithm into fast O (N) versions of the IIR algorithm. Therefore, we derive a fast version of the algorithm fro...
متن کاملSliding window adaptive fast QR and QR-lattice algorithms
Sliding window formulations of the fast QR and fast QR-lattice algorithms are presented. The derivations are based on the partial triangularization of raw data matrices. Three methods for window downdating are discussed: the method of plane hyperbolic rotations, the Chambers’ method, and the LINPACK algorithm. A numerically ill-conditioned stationary signal and a speech signal are used in finit...
متن کاملApproximate QR-Based Algorithms for Recursive Nonlinear Least Squares Estiamtion
This paper proposes new approximate QR-based algorithms for recursive nonlinear least squares (NLS) estimation. Two QR decomposition-based recursive algorithms are introduced based on the classical Gauss-Newton (GN) and Levenberg-Marquardt (LM) algorithms in nonlinear unconstrained optimization or least squares problems. Instead of using the matrix inversion formula, recursive QR decomposition ...
متن کاملAdvanced Algorithms for Adaptive Filtering
In this paper, we evaluate the possibility to develop algorithms of adaptation for the applications system of acoustic echo cancellation, while maintaining equilibrium between its reduced calculation complexity and its adaptive performances. We present new algorithms versions of fast recursive least squares numerically stable (NS-FRLS). They are obtained by means of redundant formulas, availabl...
