This paper proposes a method for online feedback path modeling in multichannel active noise control (ANC) systems. Previously we have proposed a method for online feedback path molding for single-channel ANC system. Here we modify and extend this method to multichannel ANC systems, in particular, we consider a 1 × 2 × 2 system comprising one reference(More)
BACKGROUND Pregnancy induced hypertension results from defective trophoblast invasion and increased umbilical artery resistance which in turn results in decreased blood supply to the placenta and hence to the foetus. This arterial resistance varies in different cases of PIH thus causing variable effects on placenta and foetus. The objective of this study(More)
This paper proposes a new method for online modeling of the acoustic feedback path in active noise control (ANC) systems. The proposed method comprises three adaptive filters: 1) the FxLMS algorithm based noise control filter, 2) a variable step size (VSS) LMS algorithm based feedback path modeling (FBPM) filter, and 3) LMS algorithm based adaptive noise(More)
