Abstract

The present invention is a user equipment (UE) comprising a system for establishing a communication link. The system includes a first, second and third module and a controller. The first module first processes a communication signal and generates an index value associated with a primary synchronization code within the communication signal. The second module second processes the communication signal in response to the index value and a peak sample extracted from the first module and retrieves a code group number, slot offset and secondary synchronization code. The third module third processes the communication signal and retrieves a primary scrambling code in response to the code group number and the slot offset. The controller, which is coupled to the first, second and third modules, controls the adjustment of a search frequency of the UE to retrieve the primary scrambling code in the communication signal.
