Dynamic digital communication system control

A method for controlling communication in a digital communication system using a multi-carrier modulation scheme and having first and second communication channels, the method comprising the steps of:

• creating a model characterizing interference from the first communication channel to the second communication channel, the interference created by a first signal carried on the first communication channel;
• processing the first signal, using the model, to mitigate the interference from the first communication channel to the second communication channel;
• and
• allocating energy on a plurality of frequency carriers of the second communication channel independently of the first communication channel, based on said step of processing of the first signal using the model.

An apparatus for controlling communication in a digital communication system using a multi-carrier modulation scheme and having first and second communication channels, the apparatus comprising:

• circuitry to
• create a model characterizing interference from the first communication channel to the second communication channel, the interference created by a first signal carried on the first communication channel, and
• process the first signal, using the model, for mitigating the interference from the first communication channel to the second communication channel;
• and
• an energy-allocation circuit to allocate energy on a plurality of frequency carriers of the second communication channel independently of the first communication channel, wherein said energy-allocation circuit is to allocate energy based on said processing of the first signal using the model.
