DIGITAL INFORMATION ENCODING AND TRANSMISSION METHOD Russian patent published in 2019 - IPC H03M13/00 

FIELD: information technology.

SUBSTANCE: invention relates to digital communication technology and can be used to transmit digital information over communication channels using multi-antenna systems. In the method, digital signals are pre-subjected to m-positional phase-shift keying, thereby setting a phase shift ϕ each of digital signals relative to other digital signals, are successively emitted in form of radio waves through N dipole antennas having different radiation polarization, for which antennas are located in one vertical plane and are oriented at different angles to the horizon, during radiation each of the digital signals is directed to a certain antenna having a certain inclination angle to the horizon, and hence, certain polarization, and performing the condition, according to which the minimum phase angle of shift ϕ_minN phases between two digital signals successively emitted through each antenna is greater than or equal to a given angle of phase shift.

EFFECT: technical result consists in increase of speed and noise immunity of digital information transmission due to increase of phase angle between two signals sequentially radiated through the same antenna.
