Abstract:
A method for enhancing performance of a network signal processing platform, said method comprising:a) generating and transmitting a tag signal, the tag signal for receipt by customer premises equipment;b) determining signal loss in a path of a local loop based on a first calibration signal issued by the customer premises equipment to the network signal processing platform, the first calibration signal representing tag signal loss;c) adjusting gain mapping in the network signal processor in accordance with the determined signal loss;d) generating and transmitting a wide-band signal, the wide-band signal for receipt by customer premises equipment;e) estimating, upon receipt of a second calibration signal from the customer premises equipment, spectral shaping caused by the local loop, the second calibration signal representing wide-band signal loss at a plurality of frequencies; andf) equalizing the path of the local loop.
