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 11):
The echo canceler of  claim 10 , further comprising a first digital-to-analog converter coupled to a power amplifier (PA), the power amplifier coupled to the third subtractor for providing the downstream signal to the third subtractor, wherein the first digital-to-analog converter is configured to convert the downstream signal to an analog signal, and the power amplifier is configured to amplify the downstream signal to generate the contaminated downstream signal.
