1. A method for implementing synchronization signal (“Sync Mark”) detection, the method comprising:
detecting, using a computing system, a location of a synchronization signal (“Sync Mark”) within a data signal, by using multiple frequency sinusoidal (“MFS”) signal-based filtering and a sliding window comprising successive search windows each having a bit length corresponding to a bit length of the Sync Mark to identify a portion of the data signal having a magnitude indicative of the Sync Mark, generating a first MFS coefficient of the Sync Mark and a second MFS coefficient of the Sync Mark, and producing the data signal filtered by the first MFS coefficient and the data signal filtered by the second MFS coefficient; and
refining, using the computing system, the location of the Sync Mark within the data signal, by performing a phase measurement on the identified portion of the data signal having the magnitude indicative of the Sync Mark to identify a sub-portion of the identified portion of the data signal, the identified sub-portion having a phase indicative of the Sync Mark, the phase measurement being performed based on the MFS signal-based filtering.
