충격 잡음에 강인한 ℓ1-norm 기반 볼록 조합 구조의 알고리즘

초록

In this paper, we propose a robust -norm based convex combination of two adaptive filters against impulsive interferences. Specifically, since the conventional convex combination schemes employ the -norm based adaptive filtering in updating the mixing parameter for the two adaptive filters, the performance of the overall filter may be sensitive to impulsive interferences. To overcome the problem, a novel -norm based adaptive algorithm is proposed to update the mixing parameter for the two adaptive filters. As a result, the proposed algorithm provides robust convergence performance in impulsive interference environments, which is demonstrated by computer simulations.
