1. A method for estimation of impulse noise within frames of a multi-carrier system, each of the frames being characterized by a frame number from a plurality of frame numbers, the method comprising:
- detecting the frames of the multi-carrier system that are affected by the impulse noise;
estimating one or more parameters of the impulse noise using the frame numbers of the frames that are affected by the impulse noise,wherein the one or more parameters of the impulse noise comprise a period, an offset, and a duration of the impulse noise; and
predicting a position of future frames affected by the impulse noise using the one or more parameters of the impulse noise.
