Abstract
A communication device in a communication network includes at least one processor. The at least one processor is configured to at least one processor configured to search a spectrum of the communication network using a Long Term Evolution Primary Synchronization/Secondary Synchronization Signals (LTE PSS/SSS), estimate the LTE interference using cell specific reference signals for Down Link (DL) when the LTE PSS/SSS signal is detected, and utilize LTE cell specific reference signals (CRS) and feed the equalized signal to a Data Over Cable Service Interface Specification (DOCSIS) Physical Layer (PHY) engine.
