Abstract:
Embodiments described herein provide echo cancellation power saving management at a cable transceiver. An echo response signal having a first number of signal components is obtained, via an echo cancellation filter. At a first iteration for calculating a first accumulative echo power, a respective echo tap that corresponds to the first iteration is identified. The first accumulative echo power is calculated for the respective iteration by summing powers of outputs from a last echo tap to the respective echo tap. It is then determined whether the first accumulative echo power, exceeds a pre-determined echo power threshold. If the first accumulative echo power exceeds the pre-determined echo power threshold, a first turn-off indication is sent to the echo cancellation filter to turn off all echo taps including and between the last echo tap to the first echo tap.

Claim (Index 36):
The system of  claim 31 , wherein:\n the circuit adapter is further configured to periodically send a turn-on indication to temporarily turn on all signal noise cancelling sub-circuits of the signal noise cancelling circuit; the signal noise power calculating circuit is further configured to iteratively calculate the power level based on a newly obtained noise response signal by:\n at a second iteration for calculating a second accumulative signal noise power:\n identify a second signal noise cancelling sub-circuit that corresponds to the second iteration, \n calculate the second accumulative signal noise power for the second iteration by summing powers of outputs from the last signal noise cancelling sub-circuit to the second signal noise cancelling sub-circuit, and \n determine whether the second accumulative signal noise power exceeds the pre-determined power threshold; and \n \n the circuit adapter is further configured to send an indication to adjust the signal noise cancelling circuit in a way that all signal noise cancelling sub-circuits including and between the last signal noise cancelling sub-circuit to the second signal noise cancelling sub-circuit are turned off.
