BROADBAND SIGNAL SEARCHING AND TRACING DEVICE Russian patent published in 2006 - IPC G04B1/10 H04L7/00 

FIELD: data transfer engineering; broadband radio communication systems, primarily those immune to malicious and non-malicious interference.

SUBSTANCE: proposed device has synchronizing and informative pseudorandom-sequence copy shaping units, group of correlation and tracing channels, information correlation channel, search unit, threshold shaper, delay phasing unit, comparison circuit, and decision making circuit. Novelty is introduction of subtracter, normalizing circuit, and instruction shaper. Outputs B and C of tracing-group correlation channels are connected to inputs of subtracter whose output is connected to input of normalizing circuit; other input of the latter is connected to L output of tracing-group central correlation channel. Normalizing-circuit output is connected to instruction shaper whose outputs are connected to search unit. Proposed device adjustment includes not only deviation sign but also its amount which ensures its optimal operation with noise immunity enhanced by 1 or 2 dB.

EFFECT: enhanced noise immunity of device.
