Abstract
An apparatus for system synchronization acquisition in a digital receiver and method thereof are disclosed, by which a synchronization unit is precisely locked and by which fast tracking performance is provided. The present invention includes a pre-processing unit digitally converting a reception signal by processing the reception signal in an analog area, a reception synchronization unit comprising a plurality of different synchronization units, each performing a different synchronization process sequentially by receiving the pre-processed signal, the reception synchronization unit controlling a start of the synchronization process of a next synchronization unit according to a presence or non-presence of the synchronization acquisition of a current synchronization unit, and a post-processing unit decoding the synchronization-acquired signal.
