Abstract
A chip synchronization composite code match filter and a frame synchronization composite code match filter are disclosed and respectively serve as the first and second stages of a mobile terminal which also has a third stage for providing a scrambling code identification function. These three stages complete the acquisition function for the mobile terminal. The mobile terminal is particularly suited for operational interaction in the Third Generation Partnership Project (3GPP) Standard. Both the chip synchronization and frame synchronization composite code match filters utilize the hierarchial structure of the Golay code in a manner so as to reduce the components needed to accomplish the chip and frame synchronization functions for the mobile terminal operating within the 3GPP standards.
