Abstract
A threshold noise-canceling method comprising the steps of: receiving an angle-modulated signal; identifying in the angle-modulated signal potential threshold noise events that exceed a first threshold value; calculating average values of the phase of the angle-modulated signal before and after a potential threshold noise event; identifying every potential threshold noise event as a threshold noise event when the difference between the corresponding before and after average values of the phase is greater than a second threshold value; and canceling out each threshold noise event by adding to the phase of the angle-modulated signal a 2π phase shift of polarity opposite to that of the corresponding threshold noise event.
