Adaptive spur processing

A system and method for adaptive spurious signal (spur) processing at a broadband RF receiver. Spur processing addresses the detection of spurs generated by the receiver when high level RF signals are present at its input. The spurs can lead to undesired false detections. Based on signal parameters of the received RF signal, the system detects a strong enough real signal that would cause a spur and prevent generation of false reports. The adaptive spur mitigation scheme uses multiple detection and report thresholds to enable false report rejection with an improved high probability of rejecting false detections, while minimizing the adverse effects on multi-tone dynamic range. The necessary detection and report thresholds are generated based on a system level behavioral model that predicts the performance of several different types of spurs as a function of signal parameters. The thresholds are tuned to match the behavior of the dominant spur.
