METHOD OF INCREASING FREQUENCY STABILITY OF REFERENCE GENERATORS IN COMMUNICATION SYSTEMS Russian patent published in 2024 - IPC H03L7/00 

FIELD: radio communication.

SUBSTANCE: invention relates to radio communication and can be used in systems of mutual synchronization of transceiving devices of radio lines. Periodic cyclic correction of the reference generator frequency is performed by measuring the time interval during which the maximum allowable incursion of the phase difference between the oscillations of the working reference generator and the reference generator takes place. As a result, the rate of variation of the oscillation frequency of the reference generator is estimated, which is determined by the aging of the quartz resonator and the generator elements. According to the developed algorithm, a control voltage is generated, which levels both the existing constant detuning of the frequency of oscillations of the reference generator relative to the nominal value, and step-by-step periodically changes the frequency of the controlled reference generator after a certain time interval.

EFFECT: high accuracy of clock and cyclic synchronization of transceiving devices of radio lines and ensuring minimum frequency detuning for a long time during operation in autonomous mode.
