Abstract
A novel approach for determining signal to noise ratios based on equalizer outputs and managing power for a plurality of communications channels based on communications channel performance is disclosed. According to one aspect of the invention, a noise power is generated based on an error output of an equalizer that receives input from a communications channel, and a signal power is generated based on a signal output of the equalizer. A signal to noise ratio is determined based on the noise power and the signal power. According to another aspect of the invention, a first power and a second power that is different than the first power are determined based on performance data for the plurality of communications channels. The first power is used for communications that use a first communications channel, and the second power is used for communications that use a second communications channel.
