1. A downstream transmission system for transmitting a plurality of active subcarriers over a channel, comprising:
a cable modem termination system (CMTS) configured to define a plurality of downstream profiles, wherein each of the plurality of downstream profiles includes a particular modulation order;
a plurality of modems in operable communication with the CMTS; and
a profile management unit configured to:
receive channel measurement data from each of the modems;
select an optimized set of modulation profiles from the plurality of downstream profiles based on the received channel measurement data; and
group the plurality of modems into two or more modem clusters, and wherein the optimized set of modulation profiles includes a single cluster profile for each of the two or more clusters.
