Synchronization system and method

In a system packing multiple PDUs on a single physical burst and using OFDM or OFDMA, a synchronization method comprising: a. performing an initial lock; b. processing each new header information, verifying if checksum OK, and if OK-remain in (b), system is in locked state; c. activating new header seeker, to enable running window processor to compare the expected checksum with the last byte as tentative checksum; d. declaring Tentative lock, when detecting a checksum correspondence; e. declaring Final lock, when two or more consecutive successful detections of headers, at their expected locations based on prior detections, then Goto (b).
