NOISE-LIKE SIGNAL EXTRACTION DEVICE Russian patent published in 2007 - IPC H04B1/10 

FIELD: radio communications.

SUBSTANCE: proposed device has series-connected input broadband filter, transmission gain regulator, multichannel execution unit, common limiter, broadband filter, signal recording and reading unit incorporating control function, AND circuit, mixer, controlled generator, band filter, threshold device, and threshold shaper. Novelty is introduction of adjustable amplifier and transmission gain stabilization unit. Input broadband filter is connected to signal input of transmission gain regulator whose output is connected to second input of transmission gain regulator and to first input of OR circuit. Second input of the latter is connected to output of delay line and output, to band filter through first input of mixer whose second input is supplied with generator signal. Its output is connected to first input of adjustable amplifier, second input of transmission gain stabilization unit, first input of threshold device, and threshold shaper input. Its output is connected to second input of threshold device whose output is connected to broadband filter through limiter. Adjustable amplifier output is connected to input of delay line and to output of transmission gain stabilization unit.

EFFECT: enhanced noise immunity, simplified mechanical design of equipment.
