Abstract
Systems and methods are disclosed for determining mitigating noise in multi-pair communication system. A receiver coordinated system can include 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 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. A noise decorrelation component applies the cross-correlated noise term to substantially decorrelate noise for the second line.
