摘要： A baseband processing module includes an RX interface, a rake receiver combiner module, and may include additional components. The RX interface receives the baseband signals from an RF front end and creates baseband RX signal samples there from. The rake receiver combiner module includes control logic, an input buffer, a rake despreader module, and an output buffer. The rake despreader module is operable to despread the baseband RX signal samples in a time divided fashion to produce channel symbols including pilot channel symbols and physical channel symbols.

摘要： Disclosed are various embodiments involving a window searcher for cell measurement. A window search is configurable and scalable as to a number of scrambling codes to be searched in parallel over a window span for each scrambling code. A received signal is descrambled. A coherent accumulation is performed on the descrambled received signal at a first subchip resolution to produce a coherent accumulation result. The coherent accumulation result is interpolated to a second subchip resolution. A non-coherent accumulation is performed on the descrambled received signal at the second subchip resolution based at least in part on the interpolated coherent accumulation result.

摘要： 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.
