<p>The interference detection and characterization system (13) of this invention supports modern communication systems which have to content with a variety of intentional and unintentional interference sources. As an add-on to existing communications equipment, the invention employs novel signal processing techniques to automatically detect the presence of communications channel irregularities in near real-time and alert the attending operator (26). Information provided to the operator (26) through a user-friendly interface (25) is used to characterize the type of interference and its degree of severity. Once characterized, the information is used by the operator to take corrective actions including the activation of alternative communication plans, or in some instances, mitigation of the interference. Since output from the system of this invention lends itself well to expert system and neural network environments, such systems could be employed to further aid the operator (26). Other uses include bit error rate estimators, communication channel scanners, and as laboratory test equipment to support receiver development and performance verification.</p> |
