FIELD: physics; radio.
SUBSTANCE: present invention relates to wireless communication and can be used for transmitting discrete messages through phase modulation of carrier frequencies using pseudorandom sequences. On the transmitting side the device contains a source of discrete messages, a unit for non-systematic division, four multipliers, pseudorandom sequence generator, carrier frequency generator, an adder and a power amplifier. On the receiving side, the device contains an amplifier, multiplier, three band-pass filters, a collector, demodulator, pseudorandom sequence generator and a search and synchronisation unit.
EFFECT: increased noise immunity.
