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 38):
A system for interference cancellation power saving management at a cable transceiver, the system comprising:\n an interference cancelling circuit having a number of interference cancelling sub-circuits, the interference cancelling circuit being configured to cancel electric magnetic interference components from a received signal; an interference power calculating circuit configured to:\n obtain an interference response signal having a number of signal components, the number being equivalent to the number of interference cancelling sub-circuits, \n calculate a summed power of the number of signal components indicative of an interference level of the received signal, and \n determine whether the summed power of the number of signal components exceeds a pre-determined interference threshold; \n an interference power management module configured to: in response to the determining that the summed power of the number of signal components does not exceed the pre-determined interference threshold, send a turn-off indication to turn off the interference cancelling circuit.
