Patent ID: 7782748

Claim:
A method for determining at least one operational transmit power Snk over a communication channel the method comprising: providing at least one reference victim communication channel for representing at least one reference victim for all victim communication channels which are degraded by cross-talk interferences by said communication channel; determining a maximum data rate over said at least one reference victim communication channel under a constraint that a data rate over said communication channel achieves a target rate without exceeding a power constraint; providing at least one disturbance causing transceiver communicatively coupled to the communication channel and communicatively between a central office and a customer premises equipment; determining a maximum data rate over said communication channel by maximizing a function based on the determined maximum data rate over said at least one reference victim communication channel, a number of bits allocated to a tone associated with the disturbance causing transceiver and a power associated with the disturbance causing transceiver; and determining the at least one operational transmit power Snk based on the determined maximum data rate over said communication channel.
