INFORMATION TRANSMISSION SYSTEM IN AN OPTICAL COMMUNICATION CHANNEL Russian patent published in 2022 - IPC H04B10/00 

FIELD: communication technology.

SUBSTANCE: invention relates to the field of information transmission in an optical communication channel and can be used for wireless control of land-based mobile and stationary objects. The radiation source in the system includes a device for controlling the optical axis of radiation, and the radiation receiver includes a device for controlling the optical axis of the radiation receiver, ensuring the intersection of the optical axes of the radiation source and receiver in the atmosphere at an altitude not exceeding the communication range in the ultraviolet range, the modulator converts the input information into electrical signals of potential coding, the demodulator converts potential coding signals into output information and the bandpass electrical filter is matched with the frequency band of potential coding signals.

EFFECT: increase in the noise immunity and reliability of communication by matching the angles of inclination of the optical axes of the radiation source and receiver and filtering the signal in an electric bandpass filter.
