ABSTRACT:
System and method for determining an absolute phase value of a differentially-encoded, DQPSK signal. A stored set of sequences of an ID sequence is compared with a received ID-sequence of a differentially-encoded, DQPSK signal transmitted to the receiver. The stored and the received ID sequences are correlated, and the stored values of the ID sequence are adjusted by the value of the calculated correlation.
