1. A method for reducing auto-correlation and cross-correlation in a CDMA receiver, comprising:

  • correlating an incoming CDMA signal with a locally generated signal on a first data path;

    verifying the incoming CDMA signal against a lock signal on a second data path;

    determining, using the second data path, whether the incoming CDMA signal has at least one characteristic that differentiates the incoming CDMA signal from a correlated signal selected from a group consisting of an auto-correlated and a cross-correlated signal; and

    continuing to search for a second incoming CDMA signal if the incoming CDMA signal lacks the at least one characteristic.
