@article{(Open Science Index):https://publications.waset.org/pdf/10003880, title = {Affine Projection Adaptive Filter with Variable Regularization}, author = {Young-Seok Choi}, country = {}, institution = {}, abstract = {We propose two affine projection algorithms (APA) with variable regularization parameter. The proposed algorithms dynamically update the regularization parameter that is fixed in the conventional regularized APA (R-APA) using a gradient descent based approach. By introducing the normalized gradient, the proposed algorithms give birth to an efficient and a robust update scheme for the regularization parameter. Through experiments we demonstrate that the proposed algorithms outperform conventional R-APA in terms of the convergence rate and the misadjustment error.}, journal = {International Journal of Electrical and Computer Engineering}, volume = {10}, number = {1}, year = {2016}, pages = {133 - 136}, ee = {https://publications.waset.org/pdf/10003880}, url = {https://publications.waset.org/vol/109}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 109, 2016}, }
