The affine projection (AP) algorithm is one of the most celebrated adaptive filtering
algorithms, and it achieves a good tradeoff between the convergence rate and …

Hearing loss is becoming a commonly arising problem due to noise, aging, disease, and
inheritance. Thus, usage of hearing aids have received paramount importance. In this …

Acoustic coupling between microphone and loudspeaker is a significant problem in open-fit
digital hearing aids. An open-fit compared to a close-fit hearing aid significantly lowers the …

The proportionate normalized least-mean-squares (PNLMS) algorithm is commonly used in
acoustic echo cancellation (AEC) context. It provides faster initial convergence and tracking …

A challenge in hearing aids is adaptive feedback control which often uses an adaptive filter
to estimate the feedback path. This estimate of the feedback path usually results in a bias …

Prediction error method (PEM) is popularly applied to acoustic feedback cancellation (AFC)
in hearing aids. Commonly, this method uses normalized least mean square (NLMS) …

Variable step-size (VSS) schemes are popular to use in acoustic echo cancellation (AEC)
contexts. However, their effective implementation in adaptive feedback cancellation (AFC) …

This paper proposes to use a combination of the improved proportionate normalized least
mean square (IPNLMS) algorithm and a new algorithm called combined-step-size IPNLMS …

The LMS algorithm is widely employed in adaptive systems due to its robustness, simplicity,
and reasonable performance. However, it is well known that this algorithm suffers from a …

The affine projection algorithm (APA) is commonly used for adaptive filtering in acoustic
echo cancellation (AEC) due to its higher convergence and tracking rate compared to the …
