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 16):
The system of  claim 9 , wherein the processing unit being operative to send the test signal through the echo cancelation pathway comprises the processing unit being operative to send the test signal through the echo cancelation pathway disposed in a node disposed in a Hybrid Fiber-Coaxial (HFC) network.
