Abstract:
1. A method for performing a cell search procedure in a wireless device, the wireless device comprising: a peak profiler capable of generating a peak profile of a primary synchronization channel (PSCH); and a synchronization stage for performing code group identification and scrambling code identification; the method comprising: utilizing the peak profiler to generate a peak profile of the PSCH against a predetermined primary synchronization code; selecting a first peak from the peak profile, the first peak having a first path position and an unknown associated code group number; utilizing the synchronization stage and the first path position to obtain a first code group number associated with the first peak and a first code number associated with the first peak; opening a multi-path search window of a predetermined multi-path width in the peak profile according to the first path position; selecting a second peak within the multi-path search window; performing a verification procedure on the second peak to determine if the second peak has a code number that is identical to the first code number; associating the first code group number with the second peak if the verification procedure determines that the code number of the second peak is identical to the first code number; and establishing a network connection between the wireless device and a base station corresponding to a code number of the first peak or the second peak.
