Abstract:
Analog echo cancellation with Digital-to-Analog Converter (DAC) noise suppression may be provided. First, a test signal may be sent through an echo cancelation pathway during a downstream silence period and an upstream silence period. The echo cancelation pathway may comprise an electronic element. Next, a loopback response signal may be received in response to sending the test signal through the echo cancelation pathway. Then a channel response model may be created that characterizes a channel response of the loopback response signal and a non-linear model may be created that characterizes a non-linearity of the electronic element. Next, for a downstream signal, a non-linear component may be generated based on the created non-linear model. The generated non-linear component may be convolved with the created channel response model. The convolved non-linear component may then be subtracted from an upstream signal.

Claim (Index 3):
The method of  claim 1 , further comprising scheduling a DS silence period.
