A comparative study between different pre-whitening decorrelation based acoustic feedback cancellers

Abstract

The use of an adaptive feedback canceller (AFC) based on signals pre-whitening/filtering in hearing aids seems very attractive, since it limits desired signal degradation when amplification gain is increased. In this paper, we present a comparative assessment of the performances of some existing pre-whitening decorrelation based methods. The used criteria… (More)
