Abstract:

A transmitter identification and validation system and method are operable to receive a signal transmitted by a subject transmitter and produce first and second output signals corresponding to the received signal, evaluate the first and second output signals and extract and produce respectively therefrom an observed identification (ID) code corresponding to the subject transmitter of the received signal and an observed parameter value corresponding to a parameter of the received signal, store in memory sets of ID codes and parameter values corresponding to valid transmitters, compare the observed ID code and parameter value of the received signal from the subject transmitter with the stored sets of stored ID codes and parameter values, and, as a result of the comparison, determine whether the subject transmitter of the received signal matches one of the valid transmitters. The system and method are also operable to update the stored parameter value of the one of valid transmitters with the observed parameter value of the subject transmitter in response to determining that the subject transmitter matches the one valid transmitter.
