Abstract:
A signal leakage in a cable network may be detected by using a test device to obtain a spectrum of an electromagnetic wave propagating in vicinity of the cable network, and automatically detecting QAM channels in the obtained spectrum by detecting characteristic spectral roll-offs at boundary frequencies between QAM channels of the cable network. A test device may be used to determine which QAM channels are currently active on the cable network, thereby facilitating automatic QAM signal leakage detection.

Claim (Index 25):
The method of  claim 22 , wherein identifying the change in the power present in the electromagnetic signal comprises:\n computing a cross-covariance function between:\n the frequency band; and \n a model function of the QAM channel; \n locating two neighboring peaks of the cross-covariance function; and determining that the two neighboring peaks are separated by the QAM channel frequency spacing.
