A novel normalized sign algorithm for system identification under impulsive noise interference
To overcome the performance degradation of adaptive filtering algorithm in presence of impulsive noise, a novel normalized sign algorithm (NSA) based on the convex combination strategy is proposed in this paper, which is an adaptive combination of two NSA filters with the different step-size, called NSA-NSA. The proposed approach is capable of solving the conflicting requirement of fast converg...
متن کاملSign-Sign Algorithm for Unbiased IIR Filtering in Impulsive Noise
A new equation-error based sign-sign algorithm, which is derived from a modified least-mean-squares technique, is proposed for infinite impulse response (IIR) filtering in impulsive noise. It is demonstrated that the suggested method gives unbiased IIR system parameter estimates for different types of impulsive noise. 1 This paper is a postprint of a paper submitted to and accepted for publicat...
متن کاملA new efficient filtered-x affine projection sign algorithm for active control of impulsive noise
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 ...
متن کاملAdaptive Cancellation of Geomagnetic Background Noise Using a Sign-Error Normalized LMS Algorithm
We have presented an adaptive algorithm similar to both the signerror and NLMS adaptive algorithms that is capable of reducing the geomagnetic noise present in magnetic anomaly detection systems. Through both theory and application of this algorithm to actual MAD flight data, we have proven this algorithm’s insensitivity to transients in the desired response, with a corresponding improvement in...
متن کاملModified Filtered-x Affine Projection Sign Algorithm for Active Control of Impulsive Noise
For active noise control problems, when noise sources are contaminated by impulsive noise, the classic FxLMS converges slowly or even diverges. In order to effectively control such impulsive noise sources, by minimizing the L1-norm of an error vector, a modified filteredx affine projection sign algorithm (MFxAPSA) has been proposed. An exact efficient implementation can greatly reduce its numbe...
