METHOD FOR DETECTION OF SIGNAL parcels NONSTATIONARY, Spectral and unevenly BACKGROUND

摘要

A method for detecting signal elements at unsteady, spectrally non-uniform background, consisting in the fact that the detection signal parcels carried out in a representation space, invariant with respect to shifts in time, in which the desired signal has the most compact localization compared with noise components, characterized in that criterion for the appearance of the signal above the threshold is considered exceeded the functional level, characterizing the difference signal averaged with a large time constant, the host th as the background component with respect to signal averaged with a small time constant, wherein the adaptive determination of the background component of the signal detection points is automatically turned off and ends with signals that include again.
