DISCRIMINATOR FOR SYNCHRONIZATION BY DELAY OF B-FREQUENCY DISCRETELY ENCODED SIGNAL Russian patent published in 2024 - IPC H04L7/02 

FIELD: radio engineering; communications.

SUBSTANCE: invention relates to devices for quasi-coherent reception of discretely encoded multi-frequency radio signals. The effect is achieved through the use of a method for forming a discriminatory characteristic. For this purpose, a discriminator is proposed, which additionally includes the first and the second controlled commutator, a phase shifter of 45°, a delay element and a mode switching unit, the output of which is connected to the control inputs of the first and the second controlled switches, the signal inputs of which are connected to the outputs of the carrier frequency generator and the first filter, respectively, while the output of the carrier frequency generator is connected to the second input of the third multiplier through a series-connected phase shifter at 45° and the first controlled switch, and the output of the first filter is connected to the output of the device through a delay element and the second controlled switch connected in series.

EFFECT: improved discriminator accuracy.
