Abstract:
A method is provided in one example and includes receiving a data signal, receiving an interference signal, wherein the interference signal is copied to create a reference data interference signal, combining the data signal and the interference signal to create a combined signal, using an analog echo cancellation engine on the combined signal to create an analog echo cancellation signal, and using a digital echo cancellation engine on the analog echo cancellation signal to create a data with echo cancellation signal. The data with echo cancellation signal can be communicated using a coaxial cable.
