FIELD: physics, data communication. ^ SUBSTANCE: invention relates to the field of spread-spectrum data communication performed using random carriers, in particular, to coherent data transmission systems using random signals and may be used to enhance the structured security of the carrier signal. The coherent data communication system contains a data source, a random signal accumulator and a modulator/transmitter, and a communication channel at the transmitting side and a band-pass filter, an amplifier, the first multiplier, the second multiplier, an inverter, a random signal copy accumulator, the first integrator, the second integrator, a subtractor, a resolver, and a data receiver at the receiving side. ^ EFFECT: increase in structured security of carrier signals. ^ 4 dwg |
