FIELD: digital data transmission by broad-band phase-keyed signals over high-noise radio channels. SUBSTANCE: proposed link has on sending end data source, pulse- width modulator, phase modulator, balance modulator, power amplifier, transmitter synchronizer, carrier-frequency generator, phase-keyed noise-like signal generator, and transmitting antenna; on receiving end it has receiving antenna, mixer, local oscillator, intermediate-frequency amplifier, phase-keyed reference-signal generator, correlator unit, receiver synchronizer, demodulator, and data addressee, squarer, Fourier transformer, and Fourier inverter are also provided on sending and receiving ends. EFFECT: improved noise immunity of link due to reduced probability of synchronization beyond side lobe. 4 dwg
