An apparatus for searching for a cell and a method of acquiring a code unique
to each cell in an asynchronous wideband Direct-Sequence Code Division Multiple
Access (DS/CDMA) receiver, wherein the cell searching apparatus searches for a
cell based on a received asynchronous wideband DS/CDMA signal in a receiver, the
apparatus including a code group identifying unit for estimating and compensating
for a frequency error between the synchronous channel and an internally generated
primary synchronization code, estimating and compensating for channel degradation
which the synchronous channel has experienced, and performing correlation on the
compensated synchronous channel and available secondary synchronization codes,
thereby identifying the code group; and a scrambling code identifying unit for
performing correlation on a plurality of scrambling codes belonging to the code
group, thereby obtaining a scrambling code unique to each cell.
