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 30):
The method of  claim 28 , further comprising:\n periodically sending a turn-on indication to temporarily turn on all interference cancelling sub-circuits of the interference cancelling circuit; determining whether the summed power of the second number of signal components corresponding to a newly received signal exceeds the pre-determined interference threshold; in response to determining that the summed power of the second number of signal components corresponding to the newly received signal does not exceed the pre-determined interference threshold, sending the second turn-off indication to turn off the interference cancelling circuit; and\n in response to determining that the summed power of the second number of signal components corresponding to the newly received signal exceeds the pre-determined interference threshold, keeping the interference cancelling circuit in operation.
