DISCRIMINATOR FOR SYNCHRONIZATION BY DELAY OF HIGH FREQUENCY DISCRETE-ENCODED SIGNAL Russian patent published in 2021 - IPC H04L7/02 

FIELD: aircraft industry.

SUBSTANCE: invention can find application in information radio channels of control systems for unmanned aircraft. A discriminator is proposed for synchronization by delay of a discrete-encoded high frequency signal, which contains the first, second, third, fourth, fifth and sixth multipliers, the first adder and a control element, while the output of the first adder is connected to the first inputs of the first and fifth multipliers, the outputs of which are connected to the first inputs of the second and fourth multipliers, respectively, the second inputs of which are connected to the outputs of the sixth and third multipliers, respectively, the first inputs of which are combined, moreover, the second input of the fifth multiplier is combined with the second input of the sixth multiplier, the second input of the first multiplier is combined with the second input of the third multiplier, two dividers by two, a symmetrical multivibrator, a second adder, an element AND, a reversible counter, B frequency dividers and a pulse generator, the input of which is the input of the discriminator, and the output of the pulse generator is connected to the first inputs of the third and sixth multipliers.

EFFECT: increased accuracy of discriminator synchronization.
