ADAPTIVE DEVICE FOR DATA TRANSFER WITH PSEUDORANDOM TUNING OF WORKING FREQUENCY Russian patent published in 2009 - IPC H04L9/26 

FIELD: physics, radio.

SUBSTANCE: suggested device is related to the field of radio engineering and may find application in adaptive systems of special radio communication for data transfer along radio channel under conditions of deliberate noise complex effect. Device comprises source of information, commutator of speeds, packager, the first and second demultiplexers, M coders, modulator, the first and second antenna-feeder units, clock pulses generator, generator of code sequences, control unit, the first and second analysers of signal quality, the first and second synthesisers of frequencies, generator of pseudorandom sequence, frequency transducer, amplifier of intermediate frequency, demodulator, M decoders, depackager, information receiver, unit of signal element identification, K-circuits of comparison, unit of phase self-tuning, the first, second and third multiplexers.

EFFECT: increased validity of information reception due to adaptation of clock signal to change of noise environment.
