Abstract:
1. A machine-readable storage medium having instructions stored thereon that, when executed by a machine, cause the machine to: determine whether a cable carrying a Digital Subscriber Line (DSL) signal includes complex impulse noise, wherein the complex impulse noise includes a plurality of independently periodic impulse noise components, wherein a first impulse noise component of the plurality of independently periodic impulse noise components is associated with a first noise source and occurs during a rising edge of a phase of an alternating current (AC) power line transmission at a first interval, and wherein a second impulse noise component of the plurality of independently periodic impulse noise components is associated with a second noise source and occurs during a falling edge of the phase of the AC power line transmission at a second interval that is different from the first interval; when the cable includes the complex impulse noise, correlate a time at which the complex impulse noise occurs in the cable to at least one of the first portion of the phase and the second portion of the phase; and apply one or more noise mitigation techniques to the complex impulse noise based on the correlated time.
