DISCRIMINATOR FOR DELAY SYNCHRONIZATION OF B-FREQUENCY DISCRETE-CODED SIGNAL Russian patent published in 2025 - IPC H04L7/02 

FIELD: radio engineering; electric communication technique.

SUBSTANCE: invention relates to radio engineering and communication, in particular to devices for quasi-coherent reception of discrete-coded multifrequency radio signals. Result is ensured by the fact that the discriminator for the delay synchronization of the discrete-coded B-frequency signal additionally includes a series-connected multivibrator, a switching unit and an inverter, as well as a delay element, wherein the inputs of the switching unit are connected respectively to the outputs of the tuneable carrier frequency generator and 90° phase-changing unit, wherein the second output of the switching unit is connected to the second input of the third multiplier, the output of the inverter is connected to the second input of the first multiplier, and the output of the second multiplier is connected through a delay element to the other input of the adder.

EFFECT: high accuracy of synchronizing the discriminator by using one modified correlation channel operating with advanced and delayed reference signals.
