1. A system comprising:
(a) a cable modem capable of receiving and using pre-equalization coefficients to modify an upstream signal sent by the cable modem, the upstream signal having an associated first frequency range; and (b) a head end having a cable modem termination system (CMTS) that calculates and sends the pre-equalization coefficients to the cable modem, the respective values of the pre-equalization coefficients calculated to reduce interference caused by the upstream signal to a device configured to receive a downstream signal having an associated second frequency range that at least partially overlaps the first frequency range. |
