Abstract  Abstract

A system and method for establishing initial synchronization for the link between a UE and a base station in a communication network uses window exclusion logic in order to avoid a deadlock condition upon a detection of the wrong public land mobile network (PLMN). The communication signal is processed in a three step decision process. The first decision step determines a chip offset of the strongest path detected over a frame of samples. In response to the first decision the second step generates a scrambling code group number and slot offset for retrieving the secondary synchronization code. The third decision step retrieves a primary scrambling code in response to the code group number for synchronizing the UE to the base station.
