DEVICE FOR DEMODULATION OF NOISE-LIKE SIGNAL Russian patent published in 2006 - IPC H04B1/10 

FIELD: radio communications engineering, possible use in broadband radio communication systems.

SUBSTANCE: device for demodulation of noise-like signal consists of two multipliers, two band filters. Device additionally contains blocks: two adders, two phase shifters for 90°, single-vibrator of mixing frequency generator, key, two peak detectors, comparator, trigger and two frequency-temporal transformation blocks, each one of which includes adder, mixer, band filter, delay line, adjustable amplifier, automatic amplification adjustment voltage generator.

EFFECT: increased interference resistance of information selection in communication systems with synchronous information transfer.
