METHOD OF MANAGING OBSERVATION CLUSTERING WHEN FILTERING FREQUENCY-MODULATED SIGNALS Russian patent published in 2012 - IPC H03L7/00 G06F17/17 

FIELD: information technology.

SUBSTANCE: invention relates to radio engineering and can be used to filter information processes transmitted using frequency-modulated signals. The method involves prediction of the estimate of the modulating signals on the i-th (i=1, 2,…) extrapolation interval with duration h; determining on that interval the derivative of the reference radio signal dependant on said predicted estimate, synchronously with time sampling of said derivative and the input signal with frequency F>1/h, determining products of their readings; generating a signal on the i-th extrapolation interval which is proportional to the sum of these products; improving the predicted estimate of the modulating signal using said sum; frequency-modulation, using the predicted estimate of the modulating signal, of a pulsed signal which controls sampling of the input signal and the derivative of the reference radio signal.

EFFECT: high processing accuracy owing to adaptive clustering of observations when filtering frequency-modulated signals.
