Abstract:
Disclosed herein is a multi-stage echo cancelation scheme. The disclosed embodiments include an apparatus and method for monitoring and canceling echoes greater than 25 dB in a coaxial cable plant. The method includes obtaining echo channel estimate coefficients from a cable node. The method determines a location and strength of each partial echo in an impulse response using the echo channel estimate coefficients. Optionally, the method determines a frequency response of each partial echo in the impulse response.

Claim (Index 25):
The echo canceler of  claim 24 , wherein the S 3  is configured to receive the downstream digital noise cancelation signal and the contaminated digital upstream signal, the S 3  further configured to remove the downstream noise signal portion of the downstream echo signal from the contaminated digital upstream signal using the downstream digital noise cancelation signal to generate the upstream signal.
