1. A method for detecting direct sequence spread spectrum signals with a searcher comprising:

  • specifying a hypothesis for a direct sequence spread spectrum signal from a specific communications network;

    generating a pseudo-random number (PN) sequence based on the hypothesis;

    providing the PN sequence to the searcher to correlate with a received signal;

    adjusting the PN sequence to conform to the specific communications network; and

    correlating the adjusted PN sequence with a received signal.
