Multiple branch PSYNC detection module

A wireless terminal operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station, the wireless terminal comprising:

• clock circuitry operable to generate a wireless terminal clock using a wireless terminal oscillator;
• a wireless interface operable to receive the WCDMA signal, the WCDMA signal produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator;
• and
• a Primary Synchronization (PSYNC) module coupled to the wireless interface and to the clock circuitry, the PSYNC module comprising a plurality of PSYNC correlation branches, each PSYNC correlation branch operable to:
• phase rotate the WCDMA signal based upon a respective frequency offset;
• correlate the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions;
• and
• produce PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions;
• and further comprising:
• a bit level processing module;
• bit level processing module memory;
• wherein during first synchronization operations, the PSYNC module uses the bit level processing module memory for storage of the PSYNC correlation energies;
• and
• wherein during second synchronization operations, the PSYNC module does not use the bit level module memory for storage of the PSYNC correlation energies.
