METHOD FOR TRANSMITTING INFORMATION IN AN OPEN OPTICAL COMMUNICATION SYSTEM Russian patent published in 2022 - IPC H04B10/00 

FIELD: information transmitting.

SUBSTANCE: invention relates to methods for transmitting information and can be used in open optical communication systems. To achieve the effect, two optical streams are combined in space: a reference and an information one at the same carrier frequency, while controlling the voltage of the first radiation source by the code sequence of the information message converted from parallel to serial code, and controlling the voltage of the second radiation source by the binary sequence of the irreducible finite field polynomial GF(2^∧N), where the degree N of the polynomial is determined based on the average length of the code sequence of the information message, and the combination of optical streams is carried out with orthogonal polarization. On the receiving side, the optical streams are separated using a spatial polarization separator. Each selected optical stream is converted into the corresponding digital signal by subtracting the binary sequence of the irreducible finite field polynomial GF(2^∧N) from the digital reference signal.

EFFECT: increase the noise immunity of communication.
