摘要：
A cell search apparatus and method in an OFDM mobile communication system are provided. In the cell search apparatus, a symbol synchronization acquirer acquires OFDM symbol synchronization by performing CP correlation for a plurality of OFDM symbol intervals. A frame cell synchronization acquirer sorts received OFDM symbols according to the acquired OFDM symbol synchronization, and acquires frame cell synchronization by performing preamble correlation for a plurality of frame cell intervals. A pilot pattern detector sorts received frame cells according to the acquired frame cell synchronization, and detects a pilot pattern for identifying a base station by monitoring a plurality of frame cells.
