Abstract: Embodiments are disclosed for active cancellation of noise in motion sensor signals. In some embodiments, a method comprises: obtaining a motion sensor signal from a motion sensor; obtaining a reference signal indicative of parasitic vibration from a vibration source mechanically coupled to the motion sensor; generating, using an adaptive noise canceller, an estimate of the parasitic vibration; and using the estimated parasitic vibration to cancel the parasitic vibration from the motion sensor signal.
