This paper investigates the mean square performance of two transversal adaptive filters for the feedback cancellation model in digital hearing aids. This convex combination allows the …
Here I am, finally writing what feels like the final chapter of a very long story, and I am not only referring to the length of this manuscript, but to the journey that had led to it. It all started …
