Patent ID: 8861663

Claim:
A method of operation in an Ethernet receiver circuit comprising: for each of a plurality of channels, sampling an input live Ethernet data signal to generate a sampled signal having a sampled correlated noise component caused by an interfering signal, and a sampled data component, the sampled correlated noise component being correlated to a previously sampled correlated noise component; equalizing the sampled signal to generate an equalized signal; summing, at a summer, the equalized signal with compensation signals from respective near-end crosstalk (NEXT) and far-end crosstalk (FEXT) filters to generate a summed signal; feeding the summed signal as an input to a slicer circuit; slicing the summed signal with the slicer circuit; determining a slicer error based on a difference between the summed signal and a signal produced at the output of the slicer circuit; feeding the slicer error to a correlated noise filter; filtering the slice error to generated a correlated noise compensation signal for feeding to the summer to cancel at least a portion of the interfering signal; wherein the summing includes summing the equalized signal with respective correlated noise compensation signals fed from the other of the plurality of channels.
