Abstract
An apparatus comprising a receiver configured to couple to an Ethernet Passive Optical network over Coaxial (EPoC) network, and receive an upstream Orthogonal Frequency Division Multiplexing (OFDM) signal comprising a plurality of OFDM Resource Elements (REs), and a processor coupled to the receiver and configured to determine a presence of a burst marker sequence in the received signal, wherein the burst marker sequence comprises interlaced pilot symbols and null symbols, and wherein determining the presence of the burst marker sequence comprises computing a power ratio between a first set of the OFDM REs and a second set of the OFDM REs, and determining that the burst marker sequence is found when the computed power ratio exceeds a pre-determined threshold.
