1. A method for removing selected signals from a received signal prior to decoding, the method comprising the steps of:

  • (a) receiving communication signals from a transmitter over a CDMA air interface;

    (b) inputting said received communication signals to a traffic signal cancellation system for canceling unwanted traffic signals thereby producing an output (O);

    (c) inputting said received communication signals to a pilot signal cancellation system for removing a global pilot signal thereby producing an output (Oadd); and

    (d) subtracting the output (Oadd) of the pilot signal cancellation system from the output (O) of the traffic signal cancellation system to provide a cancellation system output.
