The Variable Step-Size Gauss-Seidel Pseudo Affine Projection Algorithm
In this paper, a new pseudo affine projection (AP) algorithm based on Gauss-Seidel (GS) iterations is proposed for acoustic echo cancellation (AEC). It is shown that the algorithm is robust against near-end signal variations (including double-talk). Keywords—pseudo affine projection algorithm, acoustic echo cancellation, double-talk.
متن کاملA variable step-size diffusion affine projection algorithm
We propose a combination method for a diffusion affine projection algorithm. There are two steps to estimate unknown optimal weight in Adapt-then-combine strategy of diffusion adaptive filtering. In an adaptation step, variable step-size affine projection algorithm works to get an improvement of convergence rate and small steady-state error. In a diffusion step, the proposed combination method ...
متن کاملFast exact variable order affine projection algorithm
Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These kind of affine projection (AP) algorithms improve the standard AP algorithm performance at steady state by reducing the residual mean square error. Furthermore these algorit...
متن کاملAn Affine Projection Algorithm with Variable Projection Order using the MSE Criterion
This paper proposes an affine projection algorithm (APA) with variable projection order using the mean-square error (MSE) criterion. The proposed algorithm determines the projection order at every iteration to use it in the update equation of the proposed APA. The MSE criterion is employed to decide the projection order reasonably. Moreover, this algorithm checks the steady-state condition to c...
متن کاملAffine projection sign algorithm with ℓ1 minimization-based variable step-size
In this paper, a new affine projection sign algorithm with a variable step-size, robust in impulsive noise environments, is proposed. For that purpose, l1-norm of the a posteriori error vector is minimized under a box constraint on the step-size. Since the proposed l1-norm minimization problem is non-differentiable convex one, an efficient numerical procedure is developed for the affine project...
