Abstract
Various methods of detecting leakage of a signal from a Data-Over-Cable Service Interface Specification (DOCSIS) 3.1 channel are disclosed, including using a DOCSIS 3.1-defined 'exclusion band' to insert existing tagger-based test carriers, using a power signature algorithm to detect the presence of DOCSIS 3.1-defined pilot carriers, and using a time-based correlation technique to detect the presence of DOCSIS 3.1-defined cyclic prefixes.
