| 1. A method for communicating data, the method comprising:
identifying a static component of a transmission medium for wideband communications having at least two subchannels, wherein
the transmission medium includes a medium other than a copper telephone wire between a carrier facility and termination of
copper telephone wire at an access point at a user premise, and copper telephone wire in a cable riser in multi-tenant units
and multi-dwelling buildings;
determining a function of noise or attenuation versus frequency for the static component; selecting wideband modulation schemes
for the subchannels based on the function determined;
communicating a data signal over the subchannels;
identifying a dynamic component of the transmission medium for the wideband communications;
creating an adaptive filter based on the dynamic component; and
applying the adaptive filter to the communicated data signal at a receiver.
