    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. The data processor selects a set of QBOC correlations in accordance with a QBOC correlation function for the sampling period if the secondary amplitude exceeds the primary amplitude for the sampling period. The data processor uses either the BOC correlation function or the QBOC correlation function, whichever with greater amplitude, at each sampling period to provide an aggregate correlation function that supports unambiguous code acquisition of the received signal.

    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.
