PHASE- AND FREQUENCY-MODULATED RECEIVING DEVICE Russian patent published in 2006 - IPC H04B7/165 

FIELD: radio communications; broadband radio stations, enhanced security and noise immunity data transfer systems.

SUBSTANCE: proposed device characterized in extended spectrum of data signals transferred due to tuning their central frequencies obeying linear law and reversing polarity of frequency tuning rate, as well as due to combination of matched filtering including weight processing and time selection of signals and noise being received has synchronizer, switching unit, modulator, mixer, output matching unit, linear frequency-modulated oscillator, and frequency synthesizer on sending end. Modulator has band filters, switches, adder, and inverter. On receiving end device has linear matching unit, second mixer, band filters, intermediate-frequency amplifiers, amplitude detectors, integrators, flip-flops, dispersing compression filters, two switches, AND unit, frequency divider, OR unit, and second frequency synthesizer.

EFFECT: enhanced noise immunity in spot jamming environment.
