An Affine Projection Algorithm with Variable Projection Order using the MSE Criterion
نویسندگان
چکیده
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 change the MSE criterion for improving the performance of APA. The experimental results show that the proposed algorithm achieves faster convergence rate, smaller steady-state estimation error and lower computational complexity than the existing APAs.

متن کاملA High-Velocity Impact Simulation using SPH-Projection Method
In this paper, a new smoothed particle hydrodynamics (SPH) algorithm for simulation of elastic-plastic deformation of solids was proposed. The key point was that materials under highvelocity impact (HVI) behave like fluids. This led to propose a method which was similar to the socalled SPH-projection method, in which the momentum equations are solved as the governing equations. The method consi...
متن کاملNonlinear Adaptive Filtering with a Family of Kernel Affine Projection Algorithms
In this chapter, the family of kernel affine projection algorithms with coherence criterion is presented. The proportionality principle is translated to the kernel-based version. A new algorithm called Kernel Proportionate Affine Projection Algorithm (KPAPA) is proposed. It is proved that the additional computational increase burden is independent of the order of the algorithm, being dependent ...
متن کاملA stochastic analysis of the affine projection algorithm for Gaussian autoregressive inputs
This paper studies the statistical behavior of the Affine Projection (AP) algorithm for μ = 1 for Gaussian Autoregressive inputs. This work extends the theoretical results of Rupp [3] to the numerical evaluation of the MSE learning curves for the adaptive AP weights. The MSE learning behavior of the AP(P+1) algorithm with an AR(Q) input (Q ≤ P) is shown to be the same as the NLMS algorithm (μ =...
