Method for echo cancellation

A method and apparatus for canceling noise in a communication device is disclosed. Impulse responses to a mechanical non-linear echo in an echo-free environment are measured prior to an initial use of a communication device. A plurality of high energy parameters from these responses are extracted. A mean value of these parameters is computed and pre-stored in non volatile memory of the communication device during production of the device. During an initial use of the communication device, the pre-stored values are downloaded to the static DSP RAM and used to offset the non-linear echo.
