FIELD: physics.
SUBSTANCE: invention relates to the field of radio communication. Data transmission system with orthogonal codes is characterized by that it comprises a shift register of the transmitter, M adders modulo two, a generator of orthogonal binary sequences, M polar code generators, a radio signal demodulator, M correlation decoders, a generator of orthogonal binary sequences in a polar code, a receiver shift register.
EFFECT: technical result of invention consists in improvement of noise immunity of radio communication system.
