FIELD: information technology.
SUBSTANCE: radio-frequency signal is converted to a video frequency range and envelope signal is picked up. Said signal is discretised on time and amplitude into two levels "1" and "0". The obtained code is recorded in a shift register and dynamically compared with a discretely variable sample separately on a forward or inverse code. The comparison results are summed with subsequent removal of the constant component of the output signal, which realises the autocorrelation function of the input signal, and compared with a threshold, results of which pass through a gate circuit which closes during discrete replacement of code combinations of the samples, the output of which is the output of the device.
EFFECT: higher noise-immunity of the signal and the system as a whole.
