Patent ID: 7894508

Claim:
A baseband processing module for use within a Wideband Code Division Multiple Access (WCDMA) Radio Frequency (RF) transceiver, the baseband processing module comprising: TX processing components communicatively coupled to an RF front end of the RF transceiver and operable to receive outbound data, to process the outbound data to produce a baseband TX signal, and to output the baseband TX signal to the RF front end of the RF transceiver; a processor; memory communicatively coupled to the processor; an RX interface communicatively coupled to the RF front end of the WCDMA RF transceiver and operable to receive a baseband RX signal from the RF front end carrying a WCDMA signal; and a cell searcher module communicatively coupled to the processor and to the RX interface, the cell searcher module operable to: receive the baseband RX signal; scan for WCDMA energy within the baseband RX signal; acquire slot synchronization to the WCDMA signal based upon correlation with a Primary Synchronization Channel (PSCH) of the WCDMA signal using a phase I acquisition module; acquire frame synchronization to, and identify a code group of, the WCDMA signal based upon correlation with a Secondary Synchronization Channel (SSCH) of the WCDMA signal using a phase II acquisition module that is separate and distinct from the phase I acquisition module; acquire frame synchronization to, and identify the code groups of, a plurality of WCDMA signals of a plurality of neighbor cells bases upon correlation with the SSCH of the WCMDA signals using the phase II acquisition module; and identify the scrambling code of the WCDMA signal based upon correlation with a Common Pilot Channel (CPICH) of the WCDMA signal using a phase III acquisition module that is separate and distinct from both the phase I and phase II acquisition modules.
