Abstract:
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.
