ADAPTIVE DETECTION THRESHOLD FOR NON-STATIONARY SIGNALS IN NOISE

Abstract:

Techniques for target input detection, including receiving input data, dividing the input data into data blocks, determining a detection feature value for a first data block, determining a detection threshold based on a set of detection feature statistics determined for a background sampling time period, and determining a target signal has been received based on a comparison between the detection feature value for the first data block to the detection threshold.
