1. A receiver coordinated system to reduce crosstalk interference, comprising:
an error estimator that estimates noise for a first line of a plurality lines and provides an error estimate for the first line;
a noise predictor that applies a predetermined cross-correlation value to the error estimate to provide a correlated noise term that describes noise cross-correlation between the first line and a second line of the plurality of lines; and
a noise decorrelation component that applies the cross-correlated noise term to substantially decorrelate noise for the second line.
