Abstract:
1. A multiline communication system for reducing signal distortion, the system comprising: a first and second pair of lines in a multiline communication system; a first and second transceiver electrically connected to the corresponding first and second pair of lines; a split-pair receiver electrically connected to a line of the first pair of lines and a line of the second pair of lines and configured to identify crosstalk on the first and second transceivers; a frequency equalizer; and a post-processing unit configured to perform MIMO post-processing on signal vectors received at each transceiver of the pair of transceivers and the split-pair receiver, wherein the split-pair receiver receives a signal including the crosstalk from the first and second transceivers and provides a corresponding signal vector to the post-processing unit, and wherein the post processing unit is further configured to minimize crosstalk on the first and second pair of lines in the multiline communication system with the frequency equalizer, and wherein the line of the first pair of lines is a transmitting line and the line of the second pair of lines is a receiving line.
