A Modified Gain Normalized Step Size Adaptive Algorithm for Improved Online Secondary Path Modelling in Active Noise Control

Asutosh Kar, Gagandeep Singh, Pradeep K. Shill, Somanath Pradhan, Vasundhara, Mads Græsbøll Christensen
ICASSP 2025accepted

The noise cancellation performance of an active control system decreases when there are temporal variations in the primary and secondary paths. An active noise control (ANC) framework has been introduced in this work, which incorporates four adaptive filters and two decorrelation filters for online…

Fractional-Order Hyperbolic Tangent Based Adaptive Algorithm for Feedback Control in Hearing Aids

Vanitha Devi R, Vasundhara, Asutosh Kar, Mads Græsbøll Christensen
ICASSP 2025accepted

A new method is suggested to improve the effectiveness of adaptive filters in dealing with unexpected disturbances at the error sensor. This method focuses specifically on the difficult scenario of α-stable noise in feedback cancellation for hearing aids. α-stable noise, which is distinguished by it…

Next-Generation ANC: Integrating Dynamic Fixed-Filter Strategies With Extended Kalman Filtering for Enhanced Noise Suppression

Fareedha, Vasundhara, Asutosh Kar, Mads Græsbøll Christensen
ICASSP 2025accepted

The hybrid selective fixed-filter active noise control with filtered reference normalized least mean square (SFANC-FxNLMS) method struggles in dynamic noise environments due to its reliance on static filters, which limits effectiveness when noise characteristics change rapidly. The generative fixed-…

Robust Exponential Hyperbolic Tangent Geman-McClure Based Identification of Nonlinear Systems

Neetu Chikyal, Vasundhara, Chayan Bhar, Asutosh Kar, Mads Græsbøll Christensen
ICASSP 2025accepted

This manuscript presents a new technique to improve the performance of adaptive filters in handling the non-Gaussian or impulsive noise environment. The conduct of the adaptive filter decays in the presence of impulsive noise or outliers. To improve the efficiency of the filtering technique, this wo…
