Abstract
In a digital data communication device, power is allocated among frequency channels by selecting an initial transmission power allocation and a corresponding data rate allocation for each channel. A first channel is identified in which a given transmission power decrement results in a data rate decrement that is proportionately smaller than corresponding data rate decrements of channels other than the first channel. The transmission power allocation of the first channel is reduced by the given transmission power decrement, and the transmission power allocation in at least one channel other than the first channel is increased by the given transmission power decrement amount.
