FIELD: digital data transfer over radio channels to space and ground communication systems using noise-like signals.
SUBSTANCE: proposed radio transmitting line that has data source, pulse-width modulator, phase modulator, balance modulator, power amplifier, phase-keyed signal generator, carrier generator, transmitter synchronizer, and transmitting antenna on transmitting end as well as receiving antenna, mixer, intermediate-frequency amplifier, corrector, demodulator, heterodyne, reference phase-keyed signal generator, receiver synchronizer, and data receiver on receiving end is provided, in addition, with switch, decoder, flip-flop, random-access memory, and random-access memory address generator introduced in transmitting and receiving ends, respectively.
EFFECT: enhanced security of data transferred.
