A method implemented in a network element (NE), comprising determining, via a processor of the NE, a channel order for a set of subscriber lines at each of a plurality of subcarriers to equalize data rates of the set of subscriber lines, wherein the set of subscriber lines is coupled to a plurality of remote NEs associated with a plurality of users, determining, via the processor, parameters for a crosstalk mitigation filter for a first subcarrier from the plurality of subcarriers according to channel responses of the set of subscriber lines at the first subcarrier and a first channel order from the channel orders for the first subcarrier, and sending, via a transmitter of the NE, parameters of the crosstalk mitigation filter to facilitate joint processing of data of the plurality of users for crosstalk mitigation.
