Abstract

A method and system are disclosed for improving the performance of a multiline transmission system by using one or more split-pair receivers (475, 477) in a multiline communications system to identify crosstalk on a pair of transceivers (423, 453) coupled to the split pair receivers receivers (475, 477), wherein each split pair receiver (475) receives a signal including the crosstalk from each transceiver (423) and provides a corresponding signal vector to a post processing unit, and performing MIMO post-processing on signal vectors received at a receiver from each transceiver (423) and each split-pair receiver (475) while minimizing crosstalk on pairs of lines in the multiline communications system with a frequency equalizer.
