  • Method and apparatus for canceling periodic interference signals in a digital data communication system
    Patent number: 6434233
    Abstract: A tone predictor may be employed in a modem system to cancel periodic interference components present in a received signal. The tone predictor may be implemented in a receiver arrangement to cancel such periodic interference and to condition a decision error signal utilized to update the adaptive equalizers. The tone predictor may also be implemented in an echo canceler arrangement to cancel such periodic interference and to condition the error signal used to update the echo canceler filter. The tone predictor includes a delay element, configured to decouple the periodic interference component from other noise components, and an adaptive filter structure configured to generate a periodic interference estimate.
