A method for establishing synchronization and a data demodulator using the same. Clock and frame synchronization is established by a UW detector. Then, a DELTA omega detector and a DELTA PHI detector detect a frequency error and a phase error, respectively, from a unique word (UW) latched and held in memory so that frequency and phase synchronization is established in phase rotation by a complex rotator. That is, clock, fame, frequency, and phase synchronization are all established using a UW in the initial frame alone. This allows a receiver to establish the above synchronization at a high speed. Further, as a delay unit compensates a delay occurred in the processing by the DELTA omega detector and the DELTA omega detector, data loss is prevented.
