| Summary: | Within a synchronization stage, m candidates are selected according to secondary correlation results that are generated in a standard code group and slot number identification process. Each candidate contains a respective code group number and slot number, and m is greater than 1. A primary scrambling code correlation process is performed with each candidate to obtain a corresponding primary correlation result for an associated primary scrambling code number. The primary scrambling code correlation process for each candidate is performed over x slots, where x is determined by the ratio f/m, f being the number of slots per frame, and x being less than f. Within integer constraints, x is ideally f/m. The respective code group number, slot number and primary scrambling code number of the candidate having the greatest primary correlation result are then selected as a synchronization result. |
