Abstract
A BOC signal acquisition and tracking apparatus and method. In the present invention, a BOC subcarrier, a QBOC subcarrier and harmonics thereof are used as subcarriers. Those subcarriers can be mixed with a received signal and integration result of each mixing result is calculated. Then, all the integration results are combined as a combined correlation. Alternatively, those subcarriers can be combined as a synthesized subcarrier. The synthesized subcarrier is mixed with the received signal, and the integration of the mixing result is calculated to obtain a synthesized correlation.
