Abstract
A system for canceling impulse noise comprises an adaptive impulse canceler and a combiner. The adaptive impulse canceler is configured to receive a common mode component of a received signal and to detect a noise impulse in the common mode component. The impulse canceler is further configured to provide, based on the noise impulse in the common mode component, an impulse noise estimation for a differential mode component of the received signal. The combiner is configured to receive the differential mode component and the impulse noise estimation and to subtract the impulse noise estimation from the differential mode component.
