Abstract
Embodiments of an apparatus, system, and method are described for a multi-carrier communication system that detects for impulse noise present on a transmission medium. Values of peak error samples may be measured to determine an approximate magnitude of the average peak error samples present on a transmission medium. An average error value of all of the error samples may be measured to determine a standard deviation of a Gaussian distribution of background noise. An amount of peak error samples may be compared to a threshold value that is based upon a standard deviation derived from the background noise to determine if impulse noise is present on a particular tone.
