    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.

    Abstract: A data processor selects a set of BOC correlations in accordance with a BOC correlation function for the sampling period if the primary amplitude exceeds or equals the secondary amplitude for the sampling period. An electronic data processor determines whether the receiver is operating in a steady-state mode by evaluating the detected primary amplitude. The data processor selects and/or processes a set of BOC correlations for the sampling period to track a carrier of the received composite signal if the receiver is operating in the steady-state mode. In one embodiment, the data processor forms a first code error using the selected BOC correlations with a first chip spacing to drive the code tracking.
