METHOD OF DETECTION OF PERIODIC PULSE SEQUENCES AND ESTIMATION OF PERIOD SEQUENCES Russian patent published in 2005 - IPC

FIELD: measurement technology; computer technology.

SUBSTANCE: method can be used in devices for detecting and evaluating parameters of random pulse flows with discrete time. Method is based upon measurement of time intervals between moments of arrival adjacent pulses of input flow and storage of primary sample (mass) of N values of time intervals. Innovation concludes in calculation of first, second,…, (N+7)-th secondary samples of values of time intervals taking values of the primary sample of time intervals among moments of arrival of the first, second, …, (N+7)-th (reference) pulse correspondingly before moments of arrival of all other pulses of initial realization of the flow. Statistical estimations of greatest common divisor (GCD) are calculated within limits of separate secondary samples of two and more time intervals. Particular rows of estimation distributions of GCD of separate secondary samples of time intervals are formed. Particular rows of distribution of estimations of GCD are integrated where grouping of their values is revealed. Decision on detection of periodical pulse sequences is made on the base of facts of grouping of GCD estimations within integrated row of distribution of their values. Average values of revealed groups of GCD estimations are taken as estimations of periods of detected pulse sequences.

EFFECT: reduced time of detection; improved precision of estimation.
