Abstract
An electronic communication device comprises echo cancellation circuitry and signal modification circuitry. The echo cancellation circuitry may be operable to generate a first signal that approximates interference present in a second signal. The signal modification circuitry may be operable to generate a first cancellation signal in a frequency band that is not used on a communication medium over which the electronic communication device is configured to communicate. The signal modification circuitry may be operable to combine the first cancellation signal with the first signal, wherein the combining of the signals results in a modified first signal that has a lower crest factor and/or peak-to-average power ratio than the first signal. The signal modification circuitry may be operable to combine the modified first signal with the second signal to reduce interference present in the second signal.
