FIELD: telecommunications.
SUBSTANCE: method consists in increasing the positioning of the signal constellation by introducing into the signal an additional polarization manipulation as a manipulation parameter forming additional signal constellations, invention proposes to use the orientation angle of a linearly polarized wave, wherein all signal constellations on the whole form a single multi-position signal at one carrier frequency.
EFFECT: high rate of transmitting discrete information without considerable expansion of the spectrum while maintaining average signal energy.
