Performance Analysis of VS-APA, QR-RLS and Approximated APA on Feedback Cancellation in Hearing Aids

Different adaptive filter algorithms are used for feedback cancellation in hearing aids. In this paper first, we will explain three different algorithms for feedback cancellation, which are robust against colored input signals. These algorithms are including the Approximated Affine Projection using...

description	Different adaptive filter algorithms are used for feedback cancellation in hearing aids. In this paper first, we will explain three different algorithms for feedback cancellation, which are robust against colored input signals. These algorithms are including the Approximated Affine Projection using Gram-Schmidt prediction, the Variable Step-size APA algorithm, and the QR-RLS algorithm. Then, we will use these algorithms in feedback cancellation in hearing aids. We use two kinds of input signals in our implementation, the sound shape signal and the music shape signal. Then, the performance of these algorithms in each case is analyzed, simulation results are presented for a better comparison.
