Abstract
A system for communicating data over power utility lines includes a plurality of endpoint devices. The endpoint devices can have modulation circuits configured and arranged to modulate data using multiple-orthogonal frequency sub-channels. The endpoint devices can also have a power line interface circuit configured and arranged to transmit the modulated data over a power utility line. A detection module can be configured and arranged to detect undesirable post modulation of a communication from one of the plurality of endpoint devices and to generate a signal responsive to the detected post modulation. The endpoint devices can then set a spacing between the multiple orthogonal frequency sub-channels in response to the signal responsive to the detected post modulation.
