Abstract
An apparatus for identifying a scrambling code used in the received CDMA-based signal. The apparatus includes a frame timing estimation unit configured to estimate a frame timing of the received CDMA-based signal, a searching unit configured to search for and select a scrambling code seed based on at least the estimated frame timing, and a seed evaluation unit configured to determine if the selected scrambling code seed is the correct seed used in the received CDMA-based signal. The searching unit is further configured to provide an identified scrambling code seed based on an indication from the seed evaluation unit that the selected scrambling code seed is the correct seed. The apparatus may also include a scrambling code generator configured to generate the scrambling code from the identified seed.
