BROADBAND RECEIVING DEVICE Russian patent published in 2007 - IPC H04B7/00 

FIELD: radio communications engineering; transceiving devices for radio communications extending range of means used for the purpose.

SUBSTANCE: proposed broadband transceiving device has coder, first phase keyer, second phase keyer, first high-frequency key, second high-frequency key, NOT gate, adder, mixer, frequency synthesizer, controlled key, pseudorandom sequence generator, and key control generator on sending end. On receiving end it has mixer, intermediate-frequency amplifier, demodulator, first and second phase detectors, first and second keys, NOT gate, OR gate, decoder, speed variation command decoder, channel quality analyzer, acknowledge signal decoder, message shaping unit, memory unit, delay line, synchronization unit, pseudorandom sequence generator, key control generator, controlled key, and frequency synthesizer. Introduction of additional units and additional interconnections has made it possible to vary FH speed in case of response noise environment thereby improving communications quality in radio channel. Radio line can function at minimal speed of frequency change-over to reduce power requirement and frequency resources of radio line.

EFFECT: enhanced immunity of radio communications to malicious response noise due to varying frequency control speed depending on existing noise situation.
