FIELD: digital data transfer.
SUBSTANCE: novelty is that one switch and n decimators are newly introduced in transmitting and receiving parts of prior-art communication line that can be used for data transfer in space and ground communication systems using noise-like signals and has in receiving part data source 1, phase modulator 2, balancing modulator 3, power amplifier 4, pseudorandom sequence generator 5, carrier generator 6, transmitter synchronizer 7, and transmitting antenna 8; in receiving part it has receiving antenna 9, mixer 10, intermediate-frequency amplifier 11, matching filter 12, resolving device 13, data user 14, heterodyne 14, and receiver synchronizer 16.
EFFECT: enhanced reliability of hiding data transferred.
