Abstract

A system and method is provided for processing a physical (“PHY”) layer signal. Various aspects of the present invention may comprise receiving a PHY layer signal, analyzing a non-content characteristic of the PHY layer signal, and determining a communication protocol associated with the PHY layer signal. The PHY layer signal may be processed according to the communication protocol to obtain a processed PHY layer signal. In one embodiment, when the communication protocol is a first communication protocol, the PHY layer signal may be processed according to the first communication protocol. When the communication protocol is a second communication protocol, the PHY layer signal may be processed according to the second communication protocol. The processed PHY layer signal may be outputted.
