Abstract:
A method that calibrates a device for echo cancellation and a device with calibration for echo cancellation are provided. Devices may be calibrated such that the echo residual error is less than a threshold determined by the calibration accuracy. Non-ideal factors such as mismatch may be eliminated during calibration.
