1. A system for identifying a scrambling code from signals received from a base station, comprising:

  • a scrambling code generator configured to generate a plurality of X-component segments in a sequential manner, the plurality of codex-component segments making up a master scrambling code; and

    a plurality of correlators arranged in a sequential manner, each correlator maintaining a corresponding X-component segment and configured to correlate a set of received signals with its corresponding X-component segment and generate corresponding correlation results, the plurality of correlators collectively performing their correlations in a parallel manner in one or more iterations;

    wherein after each performed iteration, all but one of the plurality of correlators shift their corresponding X-component segments to their respective neighboring correlators and a new X-component segment is generated by the scrambling code generator and fed to one of the plurality of correlators.
