APPARATUS AND METHOD FOR PROCESSING TIMESTAMP USING SIGNATURE INFORMATION IN PHYSICAL LAYER

摘要

PURPOSE: An apparatus and a method for processing a timestamp using signature information in a physical layer are provided to improve accuracy by reducing a delay, jitter and uncertainness according to the performance of a timestamp in a physical layer. CONSTITUTION: A first timestamp processor(10) allocates signature information for indentifying a synchronization message to a transmitting message through a pseudo random number. A first timestamp processor verifies the signature information in a physical layer, and a second timestamp processor(20) verifies a pseudo random number of a message on the physical layer. Accordingly, the second timestamp processor discriminates whether or not the message is the synchronization message.
