BROADBAND SIGNAL SEARCHING DEVICE Russian patent published in 2006 - IPC H04B1/10 

Abstract SU 1840149 A1

FIELD: radio engineering.

SUBSTANCE: proposed device that has carrier generator in transmitting section and shift register in receiving section is provided with following newly introduced components: three mixers, synthesizer, signals integrating unit, filter, limiter, and trigger pulse shaper in transmitting section as well as three filters, limiter, trigger pulse shaper, and mixer in receiving section. Inputs of first filter, second filter, and delay line incorporated in receiving section are integrated, outputs of first and second filters are connected to inputs of mixer whose output is connected through series-interconnected third filter, limiter, and trigger pulse shaper to second input of pseudorandom sequence generator, and delay line output is connected to threshold shaper input.

EFFECT: reduced search time.
