Abstract
Impulsive noise is often encountered in the practical active noise control (ANC) applications. Traditional ANC algorithms fail to control such noise. Derived by minimizing the ℓ1 norm of an estimated a posteriori error vector, a new filtered-x affine projection sign algorithm (NFxAPSA) is proposed to efficiently and effectively suppress impulsive noise. Two typical extensions, such as variable step-size design and hybrid implementation, are further adapted to strengthen the effectiveness of the new structure. Simulation results verify the superior performance of the proposed algorithm in active control of impulsive noise with both synthesized and real-world data.
