Abstract:
A cable modem termination system (CMTS) may communicate with a plurality of cable modems using a plurality of orthogonal frequency division multiplexed (OFDM) subcarriers. The CMTS may determine a performance metric of each of the cable modems. For each of the OFDM subcarriers and each of the cable modems, the CMTS may select physical layer parameters to be used for communication with that cable modem on that OFDM subcarrier based on a performance metric of that cable modem. The parameters may be selected for each individual modem and/or each individual subcarrier, or may be selected for groups of modems and/or groups of subcarriers. The parameters may include, for example, one or more of: transmit power, receive sensitivity, timeslot duration, modulation type, modulation order, forward error correction (FEC) type, and FEC code rate.

Claim (Index 24):
A system, wherein the system comprises:\n a receiver operable to sort a plurality of subcarriers into a first subset of one or more subcarriers and a second subset of one or more subcarriers, wherein the sorting is based on a physical layer parameter measured on each of the plurality of subcarriers; and a transmitter operable to send a data packet on the first subset of one or more subcarriers and operable to send an error correction packet, associated with the data packet, on the second subset of one or more subcarriers, wherein a signal-to-noise ratio (SNR) on the first subset of one or more subcarriers is less than an SNR on the second subset of one or more subcarriers.
