ABSTRACT:
Transmission parameters for a multicarrier communication channel are selected by setting a power level for each subcarrier of an active set of subcarriers, and calculating the channel capacity based on the power levels and effective noise powers. The number of active subcarriers of the set is decreased, the power levels are reset and the channel capacity is recalculated until a final set of active subcarriers result that provide the highest channel capacity.
