Beschreibung
Zusammenfassung:	A method and apparatus for frame synchronization in digital communication systems using multiple modulation formats, including the Differential Phase Shift Keying (DPSK), Duobinary Signaling (DBS), and ON/OFF Keying (OOK) modulation formats, perform a search for both a frame alignment sequence (FAS) and the inverted FAS and determine the polarity of the received digital stream.
