1. A method for determining a synchronized PN sequence, comprising the steps of:

  • demodulating a received signal by a first plurality of PN sequences of a first set of windows of PN sequences determined in accordance with a first window parameter format to provide a first set of demodulation metrics;

    analyzing said first set of demodulation metrics to determine whether said synchronized PN sequence is of said first plurality of PN sequences; and

    demodulating said received signal by a second plurality of PN sequences of a second set of windows of PN sequences determined in accordance with a second window parameter format to provide a second set of demodulation metrics;

    wherein said first window parameter format further comprises a number of passes for verification.
