Abstract

FIELD: radio communications.SUBSTANCE: novelty is that newly introduced in proposed device designed for operation in radio systems using noise-like signals in case of carrier instability due to Doppler effect are frequency-shift signal generator, comparison unit, standard voltage generator, time-frequency conversion units incorporating series-connected controlled amplifier, adder, delay line, frequency-shift unit, and switching unit whose output is connected to other input of adder; inputs of time-frequency conversion units are connected to outputs of integrators and outputs, to inputs of amplitude detectors; additional inputs of synchronization unit are connected, respectively, to inputs of switching units and comparison unit; outputs of the latter are connected to inputs of controlled amplifiers and other inputs of comparison unit are connected, respectively, to standard-voltage generator output and to adder outputs; frequency shift signal generator is connected to inputs of frequency shift units.EFFECT: enhanced noise immunity in search at instability of input noise-like signal carrier frequency.1 cl, 4 dwg
