Methods to resolve phase ambiguity problem in wireless digital communication?

Answer 1

Answer:

 the phase-ambiguity for Offset QPSK modulation systems. utilized, the phase ambiguity of the reference carrier must be. receiver, the recovered carrier may have one of four possible. 90°, 270°, sense reversal, i.e, a reversal in the direction of phase. between input and output of the demodulator
