ABSTRACT:
An echo cancellation system measures an average delivery rate of a reference data signal and an average capture rate of an input data signal. From the measured data rates, the system converts the reference data signal to a domain of the input data signal. An echo canceler cancels an echo that may be present in the input data signal based upon the converted reference data signal.
