FIELD: information technology.
SUBSTANCE: signal autocorrelation function is generated, integrated and compared with a threshold value which is specified depending on the number of demodulated logic '1' and '0' signals. To this end, a register of L memory elements which is connected to the output of a resolver is also used, said register being connected in series through a counter of unit elements in the cells of the register, a unit for calculating deviation of the correlation function and unit for correcting the voltage threshold level whose other input is connected to the output of a constant generator, to the resolver, to the second input of which the magnitude of the value of the signal autocorrelation function is applied.
EFFECT: high noise-immunity of demodulating differential phase-shift keyed signals.
