Abstract
An apparatus and method for estimating an initial frequency offset in a mobile communication system in which a user equipment (UE) performs initial cell search in order to identify a Node B with which the UE can exchange data is provided. The apparatus comprises a memory for storing a plurality of pulse duration modulation (PDM) hypotheses and storing the PDM hypotheses therein; a step#cell searcher for performing a step#cell search on each of the PDM hypotheses through a primary synchronization channel and outputting the cell search result to the memory; and an initial frequency offset estimator for determining an initial frequency offset estimation value from the cell search results for the PDM hypotheses.
