Method and apparatus for dynamically adjusting receiver sensitivity over a phone line home network

摘要

A method and apparatus for dynamically adjusting receiver sensitivity over an existing phone line home network is disclosed. The method includes what is referred to Continuous Carrier Detect (CCD) adaptation process implemented by a state machine to quickly adapt to the on the fly wire DC offset in a matter of a few milliseconds for achieving optimal receiver sensitivity. According to one embodiment, a noise threshold level is dynamically generated for detecting noises in incoming data stream from the existing phone line home network.
