    Patent number: 5648765
    Abstract: A system and method for identifying items which each have an associated transponder that transmits an information encoded signal in response to a query signal and in which at least some of the information signals may occur at least in part simultaneously includes a receiver for receiving the information signals from at least some of the transponders. A signal processor identifies a strongest information encoded signal within the received signals and records the identified strongest information signal. The signal processor then subtracts the identified strongest information signal from the received signals, iterating the identifying, recording, and subtracting steps until all of the signals that can be identified are recorded. The signal processor is capable also to identify, record, and remove time displaced information signals.
