1. A method for tracking a spread spectrum signal having an associated code at a receiver, the method comprising:

  • despreading a plurality of components of the spread spectrum signal using the associated code, each of the plurality of components having a different code phase than all others of the plurality of code phases;

    weighting each of the plurality of components based on a phase difference between that component and a center code phase associated with the plurality of components; and

    determining a tracking error based on the weighted components.
