Abstract:
A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module. The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is 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. The PSYNC module includes a plurality of PSYNC correlation branches. Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset, correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions, and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions.
