Summary: | A baseband processing module includes TX processing components, a processor, memory, an RX interface, and a cell searcher module. The TX processing components receive outbound data, process the outbound data to produce a baseband TX signal, and output the baseband TX signal to a RF front end of the RF transceiver. The RX interface receives a baseband RX signal from the RF front end carrying a WCDMA signal. The cell searcher module receives the baseband RX signal, scans for WCDMA energy within the baseband RX signal, acquires slot synchronization to the WCDMA signal based upon correlation with a Primary Synchronization Channel (PSCH) of the WCDMA signal, acquires 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, and identifies the scrambling code of the WCDMA signal based upon correlation with a Common Pilot Channel (CPICH) of the WCDMA signal. |
