Abstract |
This paper proposes a new robust affine projection algorithm (APA) through a modified criterion that consists of the Euclidean norm of the sum of the difference between the present filter-coefficient vector and the previous filter-coefficient vectors. Since the iterative update equation of the proposed APA is obtained from the modified criterion, it has robustness against the high power of measurement noises. Experimental results demonstrate that the proposed APA accomplishes smaller steady-state errors than the previous algorithms. |
