FIELD: radio engineering; equipment designed for receiving and analyzing binary-phase keyed signals.
SUBSTANCE: proposed radio receiving device has nonlinear component, recording unit, and series-connected preselector, frequency converters, and intermediate-frequency amplifier. Newly introduced in device are decision unit, adder, and n nonlinear processing channels, each incorporating series-connected nonlinear components, narrow-band filter, and switch, as well as two band filters.
EFFECT: enhanced noise immunity and reliability of signal detection in background of noise and narrow-band interference.
