FIELD: radio engineering.
SUBSTANCE: device has units for producing synchronization- and information signal peaks, search unit, threshold shaper, phasing unit by delay, comparison circuit, decision-making unit, tracking group correlators and information correlator. Two subtracters, two keys provided with means for controlling them, are introduced into the design, comparison circuit, two information correlators, unit for producing commands having appropriate functional links. No synchronization errors arise when receiving simulating noise owing to fine noiseless tuning in time being carried out on mismatch signal with synchronization channel time discriminator. On simulating noise occurring, command is produced by information signal time discriminator for replacing it with mismatch signal.
EFFECT: increased noise immunity against simulating noise.
