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.

대표청구항 ▼

A transmitter identification and validation system, comprising: (a) means for receiving a signal transmitted by a subject transmitter and producing first and second output signals corresponding to the received signal; (b) means for evaluating the first and second output signals and extracting and producing respectively therefrom an observed identification (ID) code corresponding to the subject transmitter of the received signal and at least one observed parameter value corresponding to at least one parameter of the received signal; (c) means for storing sets of ID codes and parameter values corresponding to valid transmitters; (d) means for comparing the observed ID code and observed parameter value of the received signal from the subject transmitter with said stored sets of ID codes and of parameter values and for generating, in response to the comparing, a pair of scores respectively proportional to the degree of match of the observed ID code with one of stored ID codes and to the degree of match of the observed parameter value with one of the stored parameter values; and (e) means for evaluating the respective scores generated by said comparing means and for deciding, first, based on one of the scores whether or not the subject transmitter of the received signal is recognized as matching one of the valid transmitters and, second, based on the other of the scores the likelihood that the subject transmitter of the received signal is legitimate.
