<p>In one embodiment, the method includes determining (S410), at an access node (100), a precoder matrix for precoding transmission from the access node to a plurality of downstream devices (200) over a plurality of lines. The plurality of lines include high power lines and low power lines. The high power lines are in active communication and transmit more symbols per frame than the low power lines. The method further includes precoding (S420) a signal vector using the precoder matrix regardless of the symbols the signal vector is sending over the low power lines. Here, the determining determines the precoder matrix such that the precoding does not mitigate the cross-talk effect the high power lines have on the low power lines. The method also includes transmitting (S430) over the plurality of lines based on the precoded signal vector.</p> |
