Patent ID: 7916802

Claim:
In a digital subscriber system comprising a group of cooperating modems conducting communications via a shared multicarrier binder, a method comprising: iteratively allocating power and bits to frequency bins among the group of cooperating modems so as to maximize a total data rate for the group of cooperating modems subject to a predetermined criteria; determining, for each cooperating modem, a corresponding total incremental power comprising a sum of a power required by the cooperating modem to transmit an additional number of bits in a select frequency bin and a power required by the other cooperating modems of the group to compensate for interference resulting from the transmission of the additional number of bits in the select frequency bin by the cooperating modem; identifying a cooperating modem having the lowest corresponding total incremental power for the select frequency bin; and allocating the additional number of bits to the identified cooperating modem for the select frequency bin.
