DEVICE FOR TRACKING DELAY OF NOISE-LIKE FREQUENCY-MANIPULATED SIGNALS Russian patent published in 2007 - IPC H04L7/04 

FIELD: radio engineering, possible use in receivers of noise-like frequency-manipulated signals with continuous phase.

SUBSTANCE: device contains two multipliers, generator of support signals, digital time discriminator, loop filter and block for forming code series, which contains two permanent memory elements, controllable phase shifter, divider of frequency by two, pseudo-random series generator, phase accumulation, random-access memory element, support generator, decoder, where digital time discriminator contains six digital integrators, two random-access memory elements, four multipliers, an adder, a subtracter, two demultiplexers, a computing block.

EFFECT: increased interference resistance and increased synchronization precision of support signals.
